Three mantras of the Muṇḍaka Upaniṣad (2.2.9-11) give information regarding the bodily effulgence of the Supreme Personality of Godhead. They state: hiraṇmaye pare kośe virajaṁ brahma niṣkalamtac chubhraṁ jyotiṣāṁ jyotis tad yad ātma-vido viduḥ na tatra sūryo bhāti na candra-tārakaṁ nemā vidyuto bhānti kuto ’yam agniḥtam eva bhāntam anubhāti sarvaṁ tasya bhāsā sarvam idaṁ vibhāti brahmaivedam amṛtaṁ purastād brahma paścād brahma dakṣiṇataś cottareṇaadhaś cordhvaṁ ca prasṛtaṁ brahmai- vedaṁ viśvam idaṁ variṣṭham “In the spiritual realm, beyond the material covering, is the unlimited Brahman effulgence, which is free from material contamination. That effulgent white light is understood by transcendentalists to be the light of all lights. In that realm there is no need of sunshine, moonshine, fire or electricity for illumination. Indeed, whatever illumination appears in the material world is only a reflection of that supreme illumination. That Brahman is in front and in back, in the north, south, east and west, and also overhead and below. In other words, that supreme Brahman effulgence spreads throughout both the material and spiritual skies.”
