Namaste,
I downloaded this book which is Kannada: "Shankara maha manana". I think this book is an excellent book on Advaita. In a question-and-answer format, he has explained complex concepts in a simple way. However, it is in Kannada and many people do not know Kannada.
Please let me know if this book was translated into English.
here is a list of his English books:
Here is an interesting comment on HH Sacchidanandendra swami ji by Sri Vidyasankar Sundareshan, who incidentally started the Advaita Group, immediately after a conversation on Brihadaranyaka Upanishad ( A 3-way call between myself, Sri VidyaSankar, and Sri Mani Varadarajan. Incidentally, it took place sometime in the year 1986. Not sure. I know the conference call was expensive: probably 5$ per minute. This conversation took place for a couple of hours!!)
Best Regards,
Krishna Kashyap
