Vishnu is known as the “sleeping god” — whose dream is the Universe. Vishnu’s divine energy is represented as a lotus, growing out of his navel. The creator-god Brahma sits on that lotus, and from within it creates the world.

The goddess Lakshmi
loves to make love to Vishnu
from on top
looking down she sees in his navel
a lotus
and on it Brahma the god
but she can’t bear to stop
so she puts her hand
over Vishnu’s right eye
which is the sun
and night comes on
and the lotus closes
with Brahma inside
