Tripurarahasya is based on the spiritual dialogue between Lord Shri Dattatreya and his best disciple Lord Bhargava Jamadagnya Parashuram. Shri Gurudev Shrinivasji gave discourses on ‘Gnyan Khand’ of Tripurarahasya for fifteen consecutive years. These discourses have been compiled and some of them have been included in this book ‘Rahasyarthaprakash’ – Mahabhashya (Part 1). Lord Shri Dattatreya begins to preach his disciple Bhargava Parashurama, by shedding light on the Nirguna(subtle) and Saguna(gross) forms of Chitashakti Shreevidya – the divine energy of Parabrahman. While the sermon is going on, Lord Shri Bhargava Parashuram asks questions with humble curiosity and Lord Shridattatreya answers his questions. Thus, Tripurarahasya is a dialogue between two incarnate sages and from their dialogues emerge some pertinent questions about the truth in human life. This entire book is divided into three volumes namely Gnyankhand, Mahatmyakhand and Charyakhand. The Gnyankhanda contains the explanation about the formless Parameshwari (supreme) form of Chitashakti Shreevidya, endowed with infinite power and the transcendental, unmanifest, nirguna, formless, cosmic, Parashiva or Sachchidananda Brahmaswarupa form. This book contains twelve discourses given by Shri Shrinivasaji from 12-08-1998 to 25-08-1998 which are based on chapters 12 to 14 of Tripurarahsya (Gnyankhand) – the spiritual dialogue between Lord Shri Dattatreya and Shri Parshuram. What is the true purpose of human life? What is the idea of real welfare of human beings? What is the true path of seeker’s welfare? Who are we really? Why did you come to this world? What is the nature of the world around us? What is our relationship with it? Such serious philosophical questions arose in the mind of Lord Shri Parshuram. They were resolved by Lord Dattatraya through Tripurarahasya. Those who have such questions will surely get answers from these discourses given by Shri Gurudev.
