This book " EXISTENCE "( SAT- CHIT- ANANDA) covers all the Eternal and Spiritual topics like Liberation, Love, Self Realisation, Surrender, Mind, The Ultimate Reality, Rebellion, Suffering, Fearlessness, Ego, Death, God, Human Existence and life. These topics are the core spiritual topic and It is the essence of truth that is ever said by anyone, by any medium. Truth is one and eternal but it's narration may vary from time to time and people to people. Every Enlightened being of the past have chosen their own ways to reach that Ultimate. After realising that, every Master has their own way of narration of the truth. So, whatever is being written in this book is not something new - these are the truth that is being known by hundreds of mystics in the past and also being narrated by them .This Ultimate reality will be kept realising by hundreds of people who will be coming ahead in this world. The truth is very old, still It is very new and fresh for anyone who realises it in the present moment. Truth is not like a stagnant pool which is limited by it's circumference and depth rather Truth is like ever flowing ocean which has ultimate depth and ever infinite boundary. So by this book, I have tried to indicate toward that ultimate reality so that everyone of us could get the Enligtenment .The Ultimate Truth can't be explained in words but I have tried to do it as much as I can. Hope to see you in the journey of bliss and freedom.
