Word-by-Word Meaning
Explanation & Commentary
Krishna describes the great rhythm of cosmic creation and dissolution. When Brahma's day dawns, all manifested beings (vyaktayah) emerge from the unmanifested (avyakta) source; when his night falls, they dissolve back into that same unmanifested state. Creation breathes out and breathes in, again and again.
This is the cosmic counterpart to the cycle of birth and death we know in our own lives. Just as individuals are born, live, and pass away, so entire universes arise and return to their seed-state. The unmanifested is like the deep ground from which all forms blossom and into which they fade — neither truly created nor truly destroyed, but cyclically expressed and withdrawn. By revealing this pattern, Krishna shows that the visible world, for all its apparent solidity, is a temporary phase within an endless rhythm. Recognizing this helps the seeker hold the world more lightly and look toward what stands beyond all cycles.
💡 Key Takeaway
All forms arise from and return to an unseen source in an endless rhythm, so hold the changing world lightly.
