Tripurarahasya is based on the spiritual dialogue between Lord Sri 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 3). Lord Shri Dattatreya begins to preach his disciple Bhargava Parashurama, by shedding light on the Nirguna(subtle) and Saguna(gross) forms of Chitashakti Srividya – the divine energy of Parabrahman. While the sermon is going on, Lord Shri Bhargava Parashuram asks questions with humble curiosity and Lord Sridattatreya 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 Srividya, endowed with infinite power and the transcendental, unmanifest, nirguna, formless, cosmic, Parashiva or Sachchidananda Brahmaswarupa form. Some parts of the discourse given by Shri Gurudev on the thirteenth and fourteenth chapters of Tripurarahasya Gnyankhand from 09.02.1999 to 30.08.1999 have been published in this third volume. Is the world full of joys and sorrows a fiction or a reality? Why does it seem to be in such dual form of happiness and sorrow? Who experiences it and what is the reason and purpose behind its appearance? With such questions in mind, the dialogue between Mahasen and Munikumar which started from the twelfth chapter continues in the thirteenth and fourteenth chapters. The entire Mahabhashya of Shri Gurudev based on the advice given by Lord Dattatreya in Gnyankhand chapter 13 and 14 is worth studying again and again.
