tasyaiṣa ādeśo yad etad vidyuto vyadyutadā itīn nyamīmiṣadā ity adhidaivatam ||
"This is the teaching about It: It is like a lightning flash, it appears for a moment and makes you blink "Ah!", this is with reference to the divine sphere."
What This Means:
How to understand Brahman? The Upanishad offers a vivid image: it's like lightning suddenly illuminating the darkness. For a split second, everything is revealed, and you can only gasp "Ah!" This describes glimpses of the divine in nature.
Going Deeper:
The lightning metaphor captures the sudden, self-luminous, and brief nature of spiritual insight. You can't hold onto it or possess it, it flashes and vanishes. Yet in that flash, everything is illuminated. The "Ah!" (Ā) represents the natural response of wonder.
How To Apply This:
Have you had moments when reality suddenly seemed vivid and alive? A flash of wonder at existence itself? These "lightning moments" are glimpses of Brahman. Don't try to hold them, let them illuminate and pass.
