ITRANS:
nābhir nabho ’gnir mukham ambu retodyauḥ śīrṣam āśāḥ śrutir aṅghrir urvīcandro mano yasya dṛg arka ātmāahaṁ samudro jaṭharaṁ bhujendraḥ
Translation:
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 Brahmā Your intelligence, the progenitor of mankind Your genitals, and religion Your heart. You are indeed the original puruṣa, creator of the worlds.
Purport:
Śrīla Śrīdhara Svāmī 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 Śrī Kṛṣṇa. Therefore we should surrender in Kṛṣṇa consciousness, and the Lord Himself will help us understand.
