I read the Bhagavad Gita and the Ashtavakra Gita,
Although there are some similarities between the gitas, I can't say they are fully compatible.
As far as I understand (and maybe I understand it incorrectly) The Ashtavakra Gita doesn't write about a personal god, like Krishna, but about a non-personal god.
But it's a very deep and interesting book.
What is your take on the Ashtavakra Gita, how does it compares to the Bhagavad Gita in your eyes?
