nabhir nabho ’gnir mukham ambu reto
dyauh sirsam asah srutir anghrir urvi
candro mano yasya drg arka atma
aham samudro jatharam bhujendrah
romani yasyausadhayo ’mbu-vahah
kesa viriñco dhisana visargah
praja-patir hrdayam yasya dharmah
sa vai bhavan puruso loka-kalpah
The sky is Your navel, fire Your face, water Your semen, and heaven Your head. The cardinal directions are Your sense of hearing, herbal plants the hairs on Your body, and water-bearing clouds the hair on Your head. The earth is Your foot, the moon Your mind, and the sun Your vision, while I am Your ego. The ocean is Your abdomen, Indra Your arm, Lord Brahma Your intelligence, the progenitor of mankind Your genitals, and religion Your heart. You are indeed the original purusa, creator of the worlds.
Srila Sridhara Svami explains that just as the tiny bugs living inside a fruit cannot comprehend the fruit, so we tiny living beings cannot understand the Supreme Absolute Truth, in whom we exist. It is difficult to understand the cosmic manifestation of the Lord, what to speak of His transcendental form as Sri Krsna. Therefore we should surrender in Krsna consciousness, and the Lord Himself will help us understand.
