From Myths and Symbols in Indian Art and Civilization, by Heinrich Zimmer:
When the divine life substance is about to put forth the universe, the cosmic waters grow a thousand-petaled lotus of pure gold, radiant as the sun. This is the door or gate, the opening or mouth, of the womb of the universe.
Now there’s a creation image with a sense of aesthetics! And vitality! And friendliness toward the feminine! I feel refreshed.
