Bhagavad Gita, Chapter 18, Verse 70

And he who will study this sacred dialogue of ours, by him shall I have been worshipped by the Yajna of knowledge; such is My conviction.

Simply studying this real conversation is named here as its own form of genuine worship.

Krishna doesn't require a separate ritual to count as worship, engaging seriously with this dialogue itself is named as sufficient. Real study becomes a real spiritual practice in its own right.
