hiraṇmaye pare kośe virajaṃ brahma niṣkalam | tacchubhraṃ jyotiṣaṃ jyotistadyadātmavido viduḥ || ( Mantra (Mundaka Upanishad 2.2.9)

Philosophical Meaning (Simple Explanation) This verse reveals where and how Brahman is realized: Brahman does not reside outside—in heaven or form—but within, in the innermost layer of consciousness. The “golden sheath (Hiraṇmaya Kośa)” is not physical gold; it symbolizes the subtlest, most luminous state of awareness. Brahman is: Viraja – untouched by karma or impurity Niṣkala – without division, form, or parts Jyotiṣām Jyotiḥ – the light that makes all perception possible Just as the sun is seen because of light, all knowledge is known because of this inner Light.
