Firstly, it was never completed as far as we know. We do know MMY did some translation sand commentarys of chapters 7-18 but we don't know which ones for sure and they were never published. The missing chapters of MMY's Gita were left in the hands of Charles Lutes and were mysteriously 'stolen' from him and have disappeared, presumably at least one person knows where they are (if you know let us all know).
Secondly, and more importantly, MMY never really unfolds the allegory that the Bhagavad Gita IS. MMY suggests in his translation that when Krishna advised Arjuna to "...rise and fight", it was talking about an actual war that occurred in India in long gone days. (Think about how silly that sounds, a dialogue on an actual battlefield where Arjuna becomes self-realized and Krishna has a class on Indian philosophy, really??) That is incorrect, Vyasa's classic only uses that historical reference loosely to tell a more subtle esoteric battle, that is, the battle between good and evil waged on the field (kurushetra) of the body, mind and soul. Understanding the Sanskrit meanings of the words and characters in the script unfolds the esoteric meaning, only a really intuitive realized soul can properly understand Vyasa's meaning since Sanskrit words can have different meanings. MMY only refers to this connection, BUT HE NEVER UNFOLDS IT! Why? probably because he had an *agenda* in writing the book and never intended to do a comprehensive analysis of it. He also said if *time permitted*, (what, he was 93 when he died) in order to do justice to the subject he'd have to do a commentary on the Gita in light of ALL six systems of Indian philosophy (Nyaya, Vaisheshika, Sankhya, Yoga...etc.) which would equal 24 commentaries.......it never happened! Which is Absurd, IMO. Thirdly, even though TM is not taught in the context of Religion, is used to be! MMY said that TM is, I quote, "....the greatest blessing of the Vedas", (The Vedas MMY) and that "all Religions come from the *eternal Religion* of the Vedas". (MMY The Vedas). The TM technique may not be a Religion, and like a steering wheel may not be called a car, it certainly is central to the functioning of a car. That is the relationship of the TM technique to Religion. The advanced chapters of the Gita were too Religious sounding for MMY, IMHO. For instance the title of Chapter 16v21 is, "The Threefold Gate of Hell", I wonder why MMY didn't bless us with his commentary of this chapter...hummm?
