Bhagavad Gita Chapter 15 Verse 17 

by Gita Press Gorakhpur

Purport - Bhagavad Gita Chapter 15 Verse 17

Gita 15.17 clarifies that Supreme God is actually someone else. It proves that the God who can be called Supreme is different than the knowledge giver of Bhagavad Gita. Chapter 15 Verse 17 also clarifies that this Supreme God is immortal and sustains everyone by entering the three lokas. This in true sense is the Supreme God. This proves that the God who is giving the knowledge of Bhagavad Gita is not the Supreme God. He has described regarding himself from verses 15.12 to 15.15 but in 15.17 he talks about the Supreme God.
