Kṛṣṇa refers to the dawn of creation. He says that the Lord of all creatures sent forth generations of men along with the system of sacrifice (‘Yajña’). He blessed them, saying that through this sacrifice, they would become prosperous and happy. The universe is designed as a cooperative system. Sacrifice is the currency of this cooperation. The Creator gave humans the ability to work and offer the results back to the source, and in return, the system would fulfill all their needs. It is like a ‘Circle of Life’ that includes the Divine. We are not independent exploiters of nature; we are interdependent participants in a cosmic order. Kṛṣṇa is reminding Arjuna that duty and sacrifice are woven into the very fabric of existence. To stop performing one’s role is to go against the design of the universe itself.
