Sri Aurobindo
Letters of Sri Aurobindo
Volume II - Part 3
It was not your account of the inconsistencies of the Gita, but those that have been urged against the combining of sadhanas of which the Gita is the finest example that I was speaking of. Your objection to Krishna’s pouring contradictory sadhanas on Arjuna was, I said, akin to these and not more sustainable.
All the other side questions I consider irrelevant and of no importance. The setting of the Gita is poetic and legendary and I consider it an admirable setting, but if you consider it a bad 
one, that does not matter. It makes no difference, even if you are right, to the spiritual excellence of the Gita. I care nothing whether Sanjaya and Krishna and Arjuna of the Mahabharat were myths or real persons. The only thing that is important is that the sadhana of the Gita is a real thing and can be lived and that if spiritually lived, its so-called inconsistencies are no inconsistencies but many well-related aspects of a single Divine Truth – the vision seen by Arjuna included. The rest is a matter of opinion and, as I say, of no spiritual importance.
