Some journeys begin with talent. Others begin with the right guidance at the right time.

Rajit Gupta first joined my NSEJS batch as a young student in 9th grade with curiosity, sincerity, and a willingness to learn deeply. Over the years, that curiosity evolved into extraordinary achievement — culminating in an exceptional academic journey that includes AIR 1 in Joint Entrance Examination – Advanced, 100 percentile in JEE Mains, selection in multiple prestigious Olympiad camps, qualification for International Physics Olympiad, and selection for APhO twice.

What makes Rajit’s journey especially meaningful to me is not only the scale of his achievements, but the depth of understanding and intellectual maturity he developed along the way. His testimonial beautifully reflects the philosophy I have always believed in — that true Physics education is not about memorization, but about intuition, clarity, imagination, and genuine curiosity.

I am deeply proud of Rajit and grateful to have witnessed his remarkable journey from a young Olympiad student to one of the finest performers in the country.

Respected Devansh Sir,

I am Rajit Gupta. I was your student in NSEJS batch in 9th grade. This year I appeared in JEE and I have got Rank 1 in JEE Advanced, 100 Percentile in JEE Mains, and very good scores in NSEP and NSEA.

I wish to express my deepest gratitude for the immense impact you have had on my journey.

When I started learning physics in your classes, it was completely new to me. But instead of just making me memorize concepts, you motivated me to truly understand them. Your guidance not only helped me build strong intuition but also sparked a genuine interest in the subject.

What sets you apart is the effort and dedication you put into each of your students. Your well-thought-out resources, insightful suggestions, and constant encouragement played a crucial role in my growth. Thanks to your support, I was selected for the Junior Science OCSC, Astronomy OCSC and later for the Physics OCSC twice. I qualified for IPhO this year and also got selected for APhO two times (although I wasn’t able to attend the event this year due to my JEE).

Looking back, I realize that without the strong foundation you gave me, none of this would have been possible. You gave me the perfect kickstart, and for that, I will always be grateful.

Thank you very much, Sir!

Best regards,
Rajit Gupta

Rudra Pethani is one of the most exceptional young students I have had the privilege to teach. His remarkable journey reflects not only extraordinary intelligence and hard work, but also deep curiosity, discipline, and a genuine passion for learning.

Rudra represented India at the 20th International Junior Science Olympiad (IJSO) held in Thailand and brought immense pride to the nation by winning a Gold Medal. Over the years, he has consistently demonstrated outstanding academic excellence and an exceptional ability to think deeply and intuitively about science and problem solving.

Today, his achievements have earned him acceptance into some of the finest universities in the world — including MIT, Stanford University, Oxford University, and Imperial College London — an accomplishment that very few students across the globe achieve.

What makes Rudra truly special is not only his brilliance, but also his humility, sincerity, and relentless desire to understand concepts at their deepest level.

Below is a heartfelt testimonial written by Rudra about his learning journey and experience with my physics mentorship.

My name is Rudra Pethani, and I am studying in Allen Career Institute.  

I came in contact with Devansh Sir in January 2024 for the INJSO Online Workshop, and I have been his student ever since. He has a completely different and unique approach to physics that I had never seen before. His clear and concise manner of speaking makes each and every student understand what he is trying to convey to us. Moreover, his systematic and methodical approach towards problem solving and concept building has really helped me get a strong grasp on the entirety of physics. The emphasis given to intuitive learning of all the various topics has helped me gain confidence and given me the ability to solve even the toughest of problems. 

I would like to thank Devansh Sir for imparting his vast knowledge to me. Without his guidance, I do not think I would have been able to get this wonderful achievement. 

Following is the Introduction of the book – “The Power of Now” by Eckhart Tolle. I found it so amazing that I felt compelled to share it with everyone. It is the story of enlightenment of Eckhart Tolle, in his own words.

I have little use for the past and rarely think about it; however, I would briefly like to tell you how I came to be a spiritual teacher and how this book came into existence. Until my thirtieth year, I lived in a state of almost continuous anxiety interspersed with periods of suicidal depression. It feels now as if I am talking about some past lifetime or somebody else’s life.

One night not long after my twenty-ninth birthday, I woke up in the early hours with a feeling of absolute dread. I had woken up with such a feeling many times before, but this time it was more intense than it had ever been. The silence of the night, the vague outlines of the furniture in the dark room, the distant noise of a passing train – everything felt so alien, so hostile, and so utterly meaningless that it created in me a deep loathing of the world. The most loathsome thing of all, however, was my own existence. What was the point in continuing to live with this burden of misery? Why carry on with this continuous struggle? I could feel that a deep longing for annihilation, for nonexistence, was now becoming much stronger than the instinctive desire to continue to live.

“I cannot live with myself any longer.” This was the thought that kept repeating itself in my mind. Then suddenly I became aware of what a peculiar thought it was. `Am I one or two? If I cannot live with myself, there must be two of me: the `I’ and the `self’ that `I’ cannot live with.” “Maybe,” I thought, “only one of them is real.”

I was so stunned by this strange realization that my mind stopped. I was fully conscious, but there were no more thoughts. Then I felt drawn into what seemed like a vortex of energy. It was a slow movement at first and then accelerated. I was gripped by an intense fear, and my body started to shake. I heard the words “resist nothing,” as if spoken inside my chest. I could feel myself being sucked into a void. It felt as if the void was inside myself rather than outside. Suddenly, there was no more fear, and I let myself fall into that void. I have no recollection of what happened after that.

I was awakened by the chirping of a bird outside the window. I had never heard such a sound before. My eyes were still closed, and I saw the image of a precious diamond. Yes, if a diamond could make a sound, this is what it would be like. I opened my eyes. The first light of dawn was filtering through the curtains. Without any thought, I felt, I knew, that there is infinitely more to light than we realize. That soft luminosity filtering through the curtains was love itself. Tears came into my eyes. I got up and walked around the room. I recognized the room, and yet I knew that I had never truly seen it before. Everything was fresh and pristine, as if it had just come into existence. I picked up things, a pencil, an empty bottle, marveling at the beauty and aliveness of it all.

That day I walked around the city in utter amazement at the miracle of life on earth, as if I had just been born into this world.

For the next five months, I lived in a state of uninterrupted deep peace and bliss. After that, it diminished somewhat in intensity, or perhaps it just seemed to because it became my natural state. I could still function in the world, although I realized that nothing I ever did could possibly add anything to what I already had.

I knew, of course, that something profoundly significant had happened to me, but I didn’t understand it at all. It wasn’t until several years later, after I had read spiritual texts and spent time with spiritual teachers, that I realized that what everybody was looking for had already happened to me. I understood that the intense pressure of suffering that night must have forced my consciousness to withdraw from its identification with the unhappy and deeply fearful self, which is ultimately a fiction of the mind. This withdrawal must have been so complete that this false, suffering self immediately collapsed, just as if a plug had been pulled out of an inflatable toy. What was left then was my true nature as the ever-present I am: consciousness in its pure state prior to identification with form. Later I also learned to go into that inner timeless and deathless realm that I had originally perceived as a void and remain fully conscious. I dwelt in states of such indescribable bliss and sacredness that even the original experience I just described pales in comparison. A time came when, for a while, I was left with nothing on the physical plane. I had no relationships, no job, no home, no socially defined identity. I spent almost two years sitting on park benches in a state of the most intense joy.

But even the most beautiful experiences come and go. More fundamental, perhaps, than any experience is the undercurrent of peace that has never left me since then. Sometimes it is very strong, almost palpable, and others can feel it too. At other times, it is somewhere in the background, like a distant melody.

Later, people would occasionally come up to me and say: “I want what you have. Can you give it to me, or show me how to get it?” And I would say: “You have it already. You just can’t feel it because your mind is malting too much noise.” That answer later grew into the book that you are holding in your hands.

Before I knew it, I had an external identity again. I had become a spiritual teacher.
