What you hold in your hands is not merely a book it is an invitation born from the depths of my own darkness, and the light I found waiting on the other side. A few years ago, I went through the worst phase of my life. Everything I thought I knew about myself, about others, about how the world worked it all came crashing down. I found myself questioning everything and judging everyone. The certainties I had built my life upon crumbled like sandcastles before an unforgiving tide. I reached a very low point, feeling utterly defeated by circumstances, by relationships, by my own mind. And so, I made a decision that seemed both terrifying and inevitable, I dropped everything and walked away. What followed was a journey across multiple countries through unfamiliar landscapes, foreign tongues, and the vast silence of being truly alone with oneself. I was searching for something I could not name. Meaning, perhaps. Clarity. Or simply a reason to continue. It was during this wandering that I found myself drawn back to Bani the sacred words of the Guru Granth Sahib Ji. Not as a cultural inheritance this time, but as a lifeline. I began to read with new eyes, with the desperate hunger of someone who had lost everything and had nothing left to lose. And slowly, something began to shift. I have always been a naturally curious mind, and for years, neuroscience had been a side passion that deeply fascinated me the intricate workings of the brain, the science of consciousness, the mechanisms of emotion and thought. As I immersed myself in Bani, I found myself drawn simultaneously to the latest research in neuroscience. I began reading both in parallel, moving between the ancient and the modern worlds, between spirituality and science. What I discovered astonished me. Throughout these pages, I have endeavoured to make both the spiritual concepts and the scientific explanations accessible and engaging. Whether you are a practising Sikh seeking to understand your faith through a new lens, a scientist curious about the neuroscience of spirituality, or simply someone searching for practical wisdom to live a better life, I hope you will find something of value here. This is meant to be a conversation between friends imagine we are sitting together, perhaps over a cup of cha, discussing the magnificent mysteries of the human mind and spirit. I shall try to be your guide, but ultimately, the insights you gain will be your own. My deepest hope is this that anyone who reads these pages will feel at least curious enough to begin their own journey of self-learning. Perhaps this exploration will help you as it helped me. Perhaps it will be the beginning of something transformative in your own life. Or perhaps it will simply plant a seed that grows in its own time. Whatever your path, know that you are not alone. The darkness you may be experiencing is not the end of your story. There is wisdom waiting for you ancient and modern, spiritual and scientific that has the power to illuminate even the darkest corners of the mind. So let us begin this journey together, with open minds and curious hearts. With warmth and respect, Samar Singh Kohli
