https://www.youtube.com/watch?v=T06icLZVN64 What does the entire Bhagavad Gita teach? In the very first chapter, Arjuna says, “ if I kill all these people, I will incur sin; I will go to hell. I will not fight.” Bhagavan Shri Krishna replied: hato vā prāpsyasi svargaṁ (2.37) — “If you are killed, you will attain heaven; if you win, you will enjoy the kingdom of earth.” Arjuna thought, “In this mortal world we are already seeing that there is no real happiness. And You have already explained that there is no true happiness even in heaven — te taṁ bhuktvā svarga-lokaṁ (9.21). Then why should I fight?” Bhagavan then delivered the entire teaching of the Gita’s eighteen chapters. He explained Vedanta, Nyaya, Sankhya, Mimamsa, Patanjali, and Vaisheshika — all Darshan Shastras. But Arjuna was still confused. Finally, in the eighteenth chapter, in verse 64, Bhagavan said, “Now listen. Beyond this I will not speak.” sarva-guhyataraṁ bhūyaḥ — “The most confidential instruction.” Arjuna became alert, wondering, “What is He going to say now?” Shri Krishna continued in 18.65: man-manā bhava mad-bhakto mad-yājī māṁ namaskuru — “Fix your mind on Me. Worship Me alone. Offer your love to Me.” — Only devotion to Him.
