SB 8.7.27
nabhir nabhas te svasanam nabhasvan
suryas ca caksumsi jalam sma retah
paravaratmasrayanam tavatma
somo mano dyaur bhagavan siras te
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O lord, the sky is your navel, the air is your breathing, the sun is your eyes, and the water is your semen. You are the shelter of all kinds of living entities, high and low. The god of the moon is your mind, and the upper planetary system is your head.
