Reread (May 2020) - Much more perspective now, after ~2 years from the first read. Also, I was able to read this in the original Sanskrit and it was understandable with the help of the translation, of course - though now I understood much of it without translation. That provided a much better understanding of the poetic aspects of this Gita. Highly recommended, though its negation of everything that exists(perplexingly, both duality and non-duality) can get tiring and repetitive eventually. It is undoubtedly intended to be so, to produce a desired deliberate effect in the reader. This is more of a "multiple remembrance" read, something that one reads whenever one wishes to reach the state of the book - here, a meditative state. As such, there is no option but to give it a perfect rating because I am yet to explore the true depths in this book.
A basic question that I shall aim to answer in this review, which I encountered asking myself this read - Why does Avadhuta Gita negate everything, including the Advaita(non-dual) Vedanta that this book is usually associated with? Because all knowledge or ignorance that a human can have is gained through means of the mind or direct experience. As both mind and the world that we experience are considered as false - impermanent and therefore unreal/illusory - all knowledge that humans can have is consequently unreal. Even Advaita Vedanta knows that it is not the truth in its final form - it points the finger towards the moon, but the teaching can never be the moon itself - it will always be just the finger. In truth, all knowledge is also maya(illusion). Simply, all our knowledge is just words, expressing concepts which do not exist in pure consciousness, or in the state where one does not have a mind/thoughts.
Therefore, all thoughts that we can have towards god/soul are a construct, and can never be true knowledge. As such, we know nothing(Socrates was right after all). We can only know that we are trying to know something, and rely on the testimonials of others who have transcended the very act of knowing and not-knowing, which is to transcend human existence itself. Humans try to construct some meaning out of our illusions(the aforesaid "finger towards the moon"). All religion is such an illusion, but this does not take away from the truth of what is said in it. The finger still points towards the moon, not the stars. By following the line of the finger, we will eventually reach the moon.
There is no duality, no non-duality, no words, no thoughts. Out of this deep nihilist dispassion emerges the end - the infinity plus one of all substance - the soul: unknowable, yet supreme over all.

July 2018 - Though I've given the Avadhuta Gita 4 stars, in reality it should be 3 and a half, because though this Gita has more depth than Ashtavakra Gita, the latter made a more personal connection with me and hence I preferred that.
Nonetheless— the book is an amazing short dialogue sung by Dattatreya, a humbling and fascinating meditation on the self, the all-pervasive Being, the collective consciousness.
This Gita goes further in renouncing both duality and non-duality—while subtly recommending the latter—and in fact, asks one to forget all attempts at reaching an elusive God, when our very consciousness, energy, and matter is our God, and we really need to do nothing to reach that.
The book is filled with deliberate contradictions to encourage even the erudite to give up his futile search for meaning.
Also as a bonus, in the last verse, it assured me that as I've read this Avadhuta Gita, I will not be reborn, so there's that. Thanks, Dattatreya.
