From food come forth beings; from rain food is produced; from sacrifice arises rain and sacrifice is born of action.

Beings arise from food, food comes from rain, rain comes from sacrifice, and sacrifice is born of action.

Krishna lays out a chain of dependence. Living beings depend on food, food on rain, rain on sacrifice (yajña), and sacrifice on action (karma). The sequence links the human world to the natural order through deliberate effort. Whether one reads sacrifice as ritual that brings rain or more broadly as the work that sustains life, the point is the same: action is not an obstacle to the cosmic order but a part of it. This prepares the next verses, which trace the chain back to its ultimate source.
