In the Bhagavad-gita the last instruction is to surrender fully unto Him the author of the Bhagavad-gita but unfortunate men of demonic mentality misunderstood the teachings of Bhagavad-gita as a method of sophistry and therefore the same Personality of Godhead Sri Krishna in the garb of a transcendental devotee preach the same techniques of Bhagavad-gita i.e. full surrender unto the almighty God or His different potencies in a demonstrative way.
