Chapter 3 · Verse 15
Krishna is tracing the chain of mutual sustenance: sacrifice feeds the gods, rain feeds creatures, food feeds life, and action is how this cycle turns. Here he locates where the entire chain begins.
karma brahmodbhavaṃ viddhi brahmākṣara-samudbhavam | tasmāt sarva-gataṃ brahma nityaṃ yajñe pratiṣṭhitam ||
1.Plain meaning
Know that action (karma) arises from Brahma (the Creator, the cosmic ordering principle), and Brahma arises from the Imperishable (Akshara, the unchanging absolute). Therefore the all-pervading Brahma is eternally established in sacrifice (yajna).
2.Line by line
brahmākṣara-samudbhavam
sarva-gataṃ brahma
nityaṃ yajñe pratiṣṭhitam
3.What is really happening
A.The chain of origination
Krishna is doing something specific here: he is tracing action upstream to its source. Not to make action seem small, but to show that it is held in something larger. When a person acts from that larger awareness, they are not less of an agent; they are a more honest one, because they see the whole lineage.
B.The authorship problem
Most suffering around action comes from excessive ownership: my plan, my credit, my failure. This verse cuts at the root of that. If action arises from a creative principle that itself arises from the Imperishable, then what exactly did you originate? The body through which the action moved? That was given. The intelligence that planned? Also given. This is not nihilism; it is precision about where you actually start.
C.Yajna as the universe's actual operating system
The Gita keeps returning to yajna, but not as ritual. The argument here is structural: the universe is organized as a network of mutual sustenance, and Brahma (the creative principle) is established permanently within that structure. To act selflessly is not to go against human nature; it is to align with the deeper nature of the system you are part of.
D.What 'know this' is asking
The verse opens with viddhi, a command to understand. This kind of knowing is not intellectual agreement. It is the recognition that shows up in how you hold an action, the felt sense that your doing is not self-contained. When that recognition is real, the anxiety of performance loosens, not because outcomes don't matter, but because the obsession with being the one who caused the outcome has thinned.
4.Modern parallel
Person A takes on a project at work and ties their identity completely to it: their idea, their execution, their success. When it goes well they feel inflated; when it stumbles they feel personally broken. The action is owned so tightly that there is no air in it. Person B brings the same energy and skill to the same project, but holds it differently. They see clearly that the idea emerged from years of inputs from others, the execution depends on a hundred cooperating conditions, and the outcome will serve something beyond their own reputation. They work just as hard, but the compulsive grip is not there. When it succeeds, they're glad. When it falls short, they adjust. The action runs through them rather than being confined to them.
→What comes next
Verse 16 delivers one of the Gita's sharpest challenges: the person who does not turn this wheel of mutual sustenance, who lives only for themselves, is described as living in vain. The stakes of understanding this chain are made explicit. When ready, say: "3.16"
