Explanation
Krishna introduces a cosmic perspective. Human anxiety often comes from seeing life only through short timelines. The Gita stretches the mind to see creation and dissolution across vast cycles, making personal worries smaller and spiritual purpose larger.
Read the traditional commentary
To show how vast — yet still finite — even Brahma's world is, Krishna unveils the cosmic scale of time. A single day of Brahma lasts a thousand yugas, and his night an equal span. Those who truly grasp this measure of cosmic day and night are the ones who 'know day and night' (ahoratra-vidah).
The purpose of this staggering arithmetic is to humble our sense of permanence. Periods we cannot even imagine — billions of human years — are but a single day in the life of the creator. By stretching the mind across such immensities, Krishna loosens our attachment to the brief spans we usually treat as enduring.
Against the backdrop of these cosmic cycles, the worlds that seemed everlasting in the previous verse reveal their impermanence. The lesson is one of perspective: when we see how vast and rhythmic time truly is, the urgency of seeking the timeless, that which lies beyond all days and nights, becomes clear.
