From: Brihadaranyaka Upanishad (VI, ii, 9-14)

From Roger Zelazny's Lord of Light

...

9. The world is a fire of sacrifice, the sun its fuel, sunbeams its smoke, the day its flames, the points of the compass its cinders and sparks. In this fire the gods offer faith as a libation. Out of this offering the Moon is born.
10. Rain, O Gautama, is the fire, the year its fuel, the clouds its smoke, the lightning its flame, cinders, sparks. In this fire the gods offer the Moon as a libation.
11. The world, O Gautama, is the fire, the earth its fuel, fire its smoke, the night its flame, the Moon its cinders, the stars its sparks. In this fire the gods offer rain as a libation. Out of this offering food is produced.
12. Man, O Gautama, is the fire, his open mouth its fuel, his breath its smoke, his spech its flame, his eye its cinders, his ears its sparks. In this fire the gods offer food as a libation. Out of this offering the power of generation is born.
13. Woman, O Gautama, is the fire, her form its fuel, her hair its smoke, her organs its flame, her pleasures its cinders and sparks. In this flame the gods offer the power of generation as a libation. Out of this offering a man is born. He lives for so long as he is to live.
14. When a man dies, he is carried to be offered in the fire. The fire becomes his fire, the fuel his fuel, the smoke his smoke, the flame his flame, the cinders his cinders, the sparks his sparks. In this fire the gods offer the man as a libation. Out of this offering the man emerges in radiant splendor.
