Aurovidya Conference

Our trip to Hyderabad for Aurovidya Conference has been canceled at the last minute due to COVID. They have asked us to attend a 1-hour session where all the participants gave a brief on their session what they have planned to deliver in the offline session. There were about 140 participants who attended the session. Pratap, Poovizhi, and Prabha gave a short presentation that we planned to do it offline with the people.  It was interesting to present our work with others and others also presented on integral education. The presentation on Self-awareness through STEM was well received.

A reflection received after the presentation from Chhalamayi
Reshma “I Would like to thank you for willingly and graciously participating in the Curtain Raiser of the AuroVidya Seminar.
We could get an inspirational glimpse of your presentation/session.
We very much look forward to you attending the Seminar offline soon.”

Real-Life Example of Trigonometry

A man is standing near a Hot air balloon. He looks up at the Hot air balloon and wonders “Height of the Hot air balloon?” The height of the Hot air balloon can be found without actually measuring it. What we have here is a right-angled triangle, i.e., a triangle with one of the angles equal to 90 degrees. Trigonometric formulas can be applied to calculate the height of the Hot air balloon if the distance between the Hot air balloon and man, and the angle formed when the Hot air balloon is viewed from the ground is given

 

It is determined using the tangent function, such as tan of angle is equal to the ratio of the height of the Hot air balloon and the distance. Let us say the angle is θ, then

tan θ = Height/Distance between object & Hot air balloon.
Distance = Height/tan θ

Let us assume that distance is 30m and the angle formed is 45 degrees, then

Height = 30/tan 45°
Since, tan 45° = 1
So, Height = 30 m

The height of the Hot air balloon can be found out by using basic trigonometry formulas.

Li-Fi

LiFi, also known as “Light Fidelity” is a wireless optical networking technology, which uses light-emitting diodes (LEDs) to transmit data. In 2011, professor Harald Haas made a LiFi demonstration at the TED (Technology, Entertainment, Design) Global Talk on Visible Light Communication (VLC).

When an electrical current goes through to a LED light bulb, a stream of light (photons) emits from the lamp. LED bulbs are semiconductor devices, which means that the brightness of the light flowing through them can change at extremely high speeds. The signal is sent by modulating the light at different rates. The signal can then be received by a detector that interprets the changes in light intensity (the signal) as data. Also when the LED is ON, you transmit a digital 1, and when it is OFF, you transmit a 0.

From a laptop, the audio signal transmits through the light-emitting diode (LED) where the brightness of the light flowing through them can change at extremely high speeds. We used a solar panel as a receiver, the signal is amplified and sent as audio output in the speaker.

Video demonstrates how simple LiFi work’s.

 

 

Ten day Vipassana Meditation in Stemland Auroville

Vipassana, which means to see things as they really are, is one of India’s most ancient techniques of meditation. It was taught in India more than 2500 years ago as a universal remedy for universal ills, i.e., an Art of Living.

Courses

The technique of Vipassana Meditation is taught at ten-day residential courses during which participants learn the basics of the method, and practice sufficiently to experience its beneficial results. There are no charges for the courses – not even to cover the cost of food and accommodation. All expenses are met by donations from people who, having completed a course and experienced the benefits of Vipassana, wish to give others the opportunity to also benefit.

Vipassana is one of India’s most ancient meditation techniques. Long lost to humanity, it was rediscovered by Gotama the Buddha more than 2500 years ago. The word Vipassana means seeing things as they really are. It is the process of self-purification by self-observation. One begins by observing the natural breath to concentrate the mind. With a sharpened awareness, one proceeds to observe the changing nature of body and mind and experiences the universal truths of impermanence, suffering, and egolessness. This truth-realization by direct experience is the process of purification. The entire path (Dhamma) is a universal remedy for universal problems and has nothing to do with any organized religion or sectarianism. For this reason, it can be freely practiced by everyone, at any time, in any place, without conflict due to race, community, or religion, and will prove equally beneficial to one and all.

What Vipassana is not:

  • It is not a rite or ritual based on blind faith.
  • It is neither intellectual nor philosophical entertainment.
  • It is not a rest cure, a holiday, or an opportunity for socializing.
  • It is not an escape from the trials and tribulations of everyday life.

What Vipassana is:

  • It is a technique that will eradicate suffering.
  • It is a method of mental purification which allows one to face life’s tensions and problems in a calm, balanced way.
  • It is an art of living that one can use to make positive contributions to society.

Vipassana meditation aims at the highest spiritual goals of total liberation and full enlightenment. Its purpose is never simply to cure physical disease. However, as a by-product of mental purification, many psychosomatic diseases are eradicated. In fact, Vipassana eliminates the three causes of all unhappiness: craving, aversion, and ignorance. With continued practice, the meditation releases the tensions developed in everyday life, opening the knots tied by the old habit of reacting in an unbalanced way to pleasant and unpleasant situations.

Although Vipassana was developed as a technique by the Buddha, its practice is not limited to Buddhists. There is absolutely no question of conversion. The technique works on the simple basis that all human beings share the same problems and a technique which can eradicate these problems will have a universal application. People from many religious denominations have experienced the benefits of Vipassana meditation, and have found no conflict with their profession of faith.

Thanks to Archana our Teacher for providing a wonderful Vipassana course. And to all my team members for this support and thanks to Sanjeev and Sanjay for creating an environment like this.

Reflection on Vipassana :

Vasantharaj 

I understood dhamma, the universal law of nature applicable to all irrespective of religion, beliefs, caste, etc

I learned the three important parts of Vipasana Sheela, Samadhi, and Panya. Sheela means living a life of morality. Samadhi is the mastery of the mind, which pays attention to reality as it is without getting distracted. Panya, the removal of cravings and aversions and remaining equanimous to all things we experience

I experienced anicca (impermanence) during Vipasana , legs become barely painful and dead after sometimes it has changed. Now I am exploring it in day-to-day life.

After completing Vipassana I saw change in myself in rigor in learning and concentration at work

Now I am started living with the present moment and noticing self-awareness.

Kayal vizhi

The vipassana course was really useful. I had time to explore myself and to know who I am, actually. It increased my determination power as well as concentration. I learned not to expect things but to accept things as it is, and also I  will give love without any expectation, and it should be like a one-way path. If someone does anything wrong, Instead of punishing them, I will transform them by giving them, love. And I also understood the law of impermanence.

Pratap

The first’s day when I sat down and began to meditate, I thought it will be easy because I am just going to sit and meditate. I thought I will complete these 10 days. But I couldn’t manage to focus my attention for even a few breaths and my mind started wandering.  My mind was very excited and started to capture irrelevant actions that I did in the past, but I made myself that I need to focus on my breath, which lasted only a few minutes. At some point, I started counting the number so that I could predict how many minutes are left before the end of the meditation.  I couldn’t sit for a long time, so I came out for a walk for 10 minutes and went back and started to meditate. Again after 5 minutes, my mind wandered, and the rest of the day went like this. In the evening discourse, S.N Goenka explained how hard the day was and gave clarity on how to meditate, which motivated me to practice. I couldn’t sleep properly that night.

On the second day, at 10 o clock in the morning, I thought of leaving the course. I felt heavy, and I felt my head was 10 times big and heavier with a lot of thoughts and background conversations. I couldn’t sit and I couldn’t meditate. A lot of bad thoughts came into my mind regarding my family which made me cry and felt crazy. I went to the teacher and said my experience and I wanted to leave, she gave her own example and her experience and asked me to sit for one more day. She also told me to focus on my breath. I started to meditate this time, I was able to focus on my breath and sat for a little longer.

On the third day, I was feeling less heavy and calm and wanted to meditate for a long time. I was able to notice the change in myself. I could still myself and stopped having background conversations. S.N Goenka said in one of the discourses, “This will also change “. This sentence helped me to get rid of my family attachments and learn that the world will move on even I am not there. Nothing is permanent, everything is impermeant (Aniccha).

On day four, I learned the technique of Vipassana. I was able to focus on the sensations in my body. After doing the two hours when I didn’t move, I was able to notice the “Sankara and dukkha” coming out from the deeper level to the gross level and disappeared. I started practicing Vipassana I felt lighter and lighter, and I felt equanimity. I started seeing things as they are and to be self-aware of myself and for my actions? After 10 days, I started meditating with strong determination. I need to practice practice practice ….

Poovizhi

I was doing Seva part timely. It was a new experience for me to do my daily work in the morning and practice vipassana while doing seva in the evenings. It helped me to get into my practice again. I learned and got motivated by the stories Archana tells us after the metta with the Sevas. I feel grateful.

Siva Raman

I have learned and recalled a lot of things from the Vippasana course. And to be aware of the sensation when I get emotional has to be consciously observed and has to be let go. So when assertive responses are to be made, action with compassion and love for myself and others. Learned to maintain my equanimity and awareness.

Bakya Lakshmi

My reflection is I realized that I should give time for everything for myself and others instead of reacting.

Prabaharan

My name is Prabaharan. I stand for courage and compassion for myself and for others. Vipassana is different from mindfulness meditation, which focuses on awareness, or to transcendental meditation, which uses a mantra. Instead, it dictates a blanket command of non-reaction. No matter the pain as you sit, or the fact that your hands and legs fall asleep and that your brain is crying for release. You are instructed to refocus attention on the objective sensations in your body, arising and falling, as you do a scan of your limbs in a specific order. By doing so, over 10 days, you train yourself to stop reacting to the vicissitudes of life.

Santhosh

My name is Santhosh, I stand for kindness and equity for myself and for others. I learned to meditation and noticed myself. I also noticed that I was not addicted to my phone, and it changed my food system.

Narmada

My name is Narmadha and  I stand for equality, happiness for myself and others. by attending the Vipassana meditation, I came to know it is the mental purification that allows me to face problems and tension in a calm and positive way.

By observing my breath, I can control my mind from the distraction.

Before this Vipassana, I can’t sit in place for a long time, but now I can sit and control my anger with the understanding of impermanence.

Sribhavani

My name is Sribhavani, I stand for Love and Equality for myself and others. I learned about seelam, samadhi and pragnya. From these three, I learned how to make my mind concentrated, the law of impermanence of every moment in my life, how to be more determined while practicing pragnya. Learned two wheels of dhammam, self-aware and equanimous. Learned metta bavana. How to share my peace, love,  and happiness with all beings from the bottom of my heart. What did I learn about myself is I started to experience every moment in my life from the law of aniksha. How my emotions are connected to my sensations. I am more self-aware of my emotions after this course. How to handle good and hard situations without much attached to it, while practicing bavanamaya panya.

Choudery

My name is Choudery I stand for justice and equality for myself and others while practicing vipassana I realized who I am, And for me, vipassana meditation is a new experience, I can feel sensation in each and every part of my body from head to toe and enjoy it, Vipassana makes me feel peaceful, It is totally new kind of experience for 10 days.

Arun

My name is Arun, I stand for happiness for myself and others. My insight about the vipassana is that I should not crave thinking to happen and also avoid keeping on thinking about the past and the future.

Live in the present moment to concentrate on what I’m doing.

Sandhiya

The 10 days vipassana course was really useful. I had time to explore myself and to know who I am, actually. It increased my determination power as well as concentration. I learned not to expect things but to accept things as it is, and also I  will give love without any expectation, and it should be like a one-way path. If someone does anything wrong, Instead of punishing them, I will transform them by giving them, love. And I also understood the law of impermanence.

 

Radical Transformational Leadership (Session 1- Sept 18th -20th) Reflection

Session 1 of RTL Leadership was conducted by Dr.Monica Sharma on (Sept 18th -20th) 2021, As Part of the Shifu(Master) program the 7 Shifuians attended the 3 days session and sharing the reflection.

 

My name is Santhosh, I stand for kindness and equity for myself and for others. I learned many useful tools for my life and this is my third RTL so I’m able to notice whether I’m using my tools or not and I was really inspired by Monica explanations , and I learned how to mingle with new people and also ,this session helped me to be stronger in my universal value.

 

My name is Choudhry, I stand for equality and justice for myself and others, I learned my stand and fear, when I doing this tool  I realize my fear is the default, And I lean how to use the “i” statement, with the help of CFSR  sheet I can describe my project and I can check where I am, also I can check am I respond and realize my project, then background conversation with me and others, and how I listening to others, the background conversation with an example of COVID-19, how to distinguish courage and bravery, this is the tools I learned from the RTL session.

 

My name is Arun, I stand for happiness for myself and others from the three days of the session. I learned that how I can look back at my stand and it brings me an idea of powerful conversation. On background connection, I have seen things differently and also learned new this for myself. From powerful communication I have understood about the way of my communication and what are all things I should add to it. Deep listening makes me how to overcome background conversation and connect with people. From filling the CFSR sheet I had an idea about my project and the issue I’m facing and how to overcome it with analysis. from  12 angry man movie, it gives me an idea that there will be two sides to a story and the story which I’m seeing won’t be seen by others but the way I have examine it gives way back to me to stand on my universal value.

 

My Name is Sri Bhavani, I stand for Love and equality for myself and others. I learned about myself is, Who I am! Identified my universal values within me. Whenever I make an effective conversation, I noticed my fear and background conversation. Noticing my background conversation, make me fully present through deep listening. I learned to, commit an action to let my fear go. How to make an effective conversation with the committed request. How to make the feedback statements, for the growth of others Subsystems are interconnected to the system. How to design my project using the CFSR sheet. Choose to be responsible whenever I get a complaint about my action. I learned to ground on my stand.

 

My name is NARMADHA, I stand for equality, happiness for myself and others. By attending the session I learned my 4 profiles and how to overcome my fear and commit action to let it go. From the movie 12 angry men, I learned that whatever the situation I chose to be in action not to react. I learned to create a design structure for my plan using CFSR. Learned system principles and learned how to make a committed request for my project and give feedback to others.

 

My name is Sandhiya and I stand for progress and love for myself and others, I learned to strengthen my stands and to overcome my fear. If I am expecting something from others I should check whether am good at it. I also learned to think from others’ points of view and to take every difficult situation as an adventure.

 

My name is Sivaraman and I stand for perseverance, courage, full potential, and equality for myself and others. I have learned to be aware and conscious about my values and add more values as I grow positive. CFSR has progressively tuned my project. I have revisited a lot of my rule and role according to build myself and others up.

Guest talk regarding Feminist Approach To Technology

FAT:

Feminist Approach To Technology (FAT),  FAT is organizing STEM Talk series webinar from January to March 2021, “STEM और हम, स्टेम पर लड़कियों द्वारा चर्चा ”  where women will share their journey, achievements, and challenges in the STEM domain. They will discuss how they were able to break gender barriers and fulfill their dreams.

Through these monthly talks, we are aiming that more girls get inspiration from this talk and advocate STEM education for young girls and women so that they can start thinking about education/career in STEM from an early age.

On March 14th I gave a talk over zoom.

 

STEMland in rural and what are opportunities it’s gives

STEMland at a rural place will give the children, youth, and even adults an opportunity to learn about science, technology, engineering, and mathematics.

Science and Mathematics:

There are many dropouts in a rural place where the children and youths are forced to go to work or children lose interest to learn. Children lose interest to learn as it is not interesting or not fun for the children to learn. In Stemland we make learning science and mathematics through practical means and through programs in laptops. By this, we make learning more fun and interesting to the children and youths. This also gives access to the children and youth to interact with technology programs.

For example,

We have made a practical method to show the a3-b3 using 3d printer and Alice(3d visual programming tool). The children program in Alice and show the visualization of the formula. They also have designed cubes to show the formula. By, this the children are able to understand the concept more easily.

From this, I can say that the children in rural place will have difficulties in language, but as they learn by programing, seeing and touching it makes learning more fun and therefore there is no language barrier.

This also gives the children and youth to interact with technologies. In this process they learn programming skills and designing skills. Here education will not only be theoretical but where they use their hands and minds together.

Technology:

I see most of the rural place is not equipped with latest technologies or even have access to it. I see Stemland as a societal change maker as it brings technology into rural places.

It can also be the first time for the children and youth to get access to laptops and other technologies.

How do I encourage girl children or women to stem education?

The first thing that comes into my mind when I hear this question is that I need to be encouraged in stem education first, then only I can encourage others. I truly believe that Stem education is the future. This is where there is equality in learning, where there is freedom with responsibility which is taken by the students by themselves not forced by the society, parents, or teachers.

I will share my experience with girl’s involvement in stem education. In my beginning days in STEMland, I saw girls getting actively involved in soldering the electronic equipment. I was surprised to see this. I thought that girls will basically work on laptops and do not want to get their hands dirty but here what I saw was the opposite. The girls opened an old Christmas light which was not working and fixed it. This is a true example of showing the interest of women’s child which is breaking the social and cultural norms.

 

In Stem education, we also provide sessions in leadership qualities where one discovers their potential within themselves and how to come out of fear. This helped me a lot to come out of my fear and to act from my possibilities. There is a practice or thinking in our society that girls should only do this not that and they are not fit for this job and all. Framed by society a girl is set to have boundaries and live within the boundaries. Stem education will be medium which will break the boundaries and will surely make the child work from her possibilities rather than her fear. Stem education has a wide range of opportunities, where a girl child can choose what she really wants from her heart then be forced to.

Edible Weed Walk at Evergreen with Nina Sengupta

As part of the ‘Becoming and Being a Shifu (Master)’ program a program to develop skills (programming and VLSI), competencies (using skills to create healthy workplaces and environment) and inner capacity (universal values) the participants are exploring some activities of Auroville. This short report is about the visit to Evergeen where we went for a ‘weed walk’ with Dr. Nina Sengupta who is an ecologist and an Aurovilian.

At C3STREAM Land Designs we learn, grow, work and teach and 5 of us went along with 7 Shifians to learn and grow.

Our visit started with the introduction of the book written by Dr. Nina – ‘Edible Weeds and Naturally Growing Plants in Auroville’. It was interesting to see that the book cover was hand-made, made from eco-friendly material. The treasure started unfolding with every plant she included in the book. Every book has two copies – one with precisely scaled plants in color and the other one with outlines which can be used as hands-on, color it to get closer to these plants.

We walked through the book one plant at a time and learned about the properties of edible weeds like Antigonan Leptopus. The first myth that was demystified while having this walk is not all weeds are non-edible, and many of them can be used not only for medicinal purposes but are a good source of nutrients for humans too. Generally, we ignore these weeds considering everything as another type of grass but they are all around us and we only have to recognize them and learn which parts of that particular weed are edible.

Once we recognize which parts are edible, then comes the next important thing – the appropriate quantity and frequency of weed to eat, the process of cooking if required. For example, some weeds can be used well after blanching them, while other weeds can be eaten raw.

The weed-walk was getting more and more interesting as we got to see and taste the different weeds. While we were able to observe weeds, on the other hand, we got closer to nature, and that also allowed us to express our learning. There are two major varieties of weeds – wild and cultivated weeds. Some species originated late, which are not mentioned in the Ayurveda. We need to constantly keep learning to know more about these weeds and start looking at these weeds from different perspectives whenever we see them around us.

The walk ended with the tasty herbal tea made by Archana and with the interactive conversation about edible-weeds, experiences of Nina as an ecologist, and Auroville in general. Thanks to Nina, Archana, and the Evergreen team for this wonderful opportunity.
