The Upanishads

The Sun as Brahman

The sun as a visible symbol of the divine.

The sun represents Brahman in visible form - the source of light, life, and consciousness for this world. Meditation on the sun leads to the formless light within.

The person that is seen in the sun - that is I.

Chandogya Upanishad, Chandogya Upanishad 1.6.6

The external sun symbolizes the inner light of awareness.
