In this connection, my own dearmost, divine master parama-aradhyadeva Sri Srimad Srila Bhakti Prajnana Keshava Gosvami Maharaja has given potent and pertinent instructions about Srimad Bhagavad-Gita. I will now attempt herewith to mention a few of them.
"The purpose for the advent of the Bhagavad-Gita is neither political nor military war tactics. Rather it aims at complete saranagati unto the lotus feet of the Supreme Lord Krishna the Supreme Absolute Truth and the Ultimate Reality. The Bhagavad-Gita's manifestation appeared to be due to Arjuna's illusion of lamentation. However, Arjuna can never come under the spell of illusion, and so his apparent lamentation was merely a pastime of Lord Krishna in order to enable the advent of Srimad Bhagavad-Gita. Arjuna is an eternal associate and a dear servitor of the Supreme Lord Krishna. It's understood from the statements of the Vedas: partho vatsa," that the advent of Srimad Bhagavad-Gita as Gitamrta or a giver of nectar, did not take place only just for the benefit of Arjuna. Lord Krishna Himself has said: mamekami paranam vraja. Here the import of the word ekam is to surrender unto the Supreme Lord Krishna, who is the supreme controller and this is indeed the final conclusion to be found in Srimad Bhagavad-Gita.
