You're looking for information on the Ashtavakra Gita and a possible PDF version by Swami Chinmayananda. Here's what I found:

The Ashtavakra Gita is a Sanskrit text and a significant scripture in Advaita Vedanta, a non-dualistic school of Hindu philosophy. The text is a dialogue between the sage Ashtavakra and King Janaka, who is also a seeker of truth. The scripture consists of 20 chapters and 322 verses, exploring the nature of the Self, reality, and the path to liberation.

Swami Chinmayananda Saraswati (1916-1993) was a renowned Indian monk, Vedanta teacher, and author. He was a disciple of Swami Sadananda, and his teachings were widely respected for their clarity and depth. Swami Chinmayananda wrote commentaries on several Hindu scriptures, including the Ashtavakra Gita.
