Sanskrit:
नाभिर्नभस्ते श्वसनं नभस्वान्सूर्यश्च चक्षूंषि जलं स्म रेत: ।परावरात्माश्रयणं तवात्मासोमो मनो द्यौर्भगवन् शिरस्ते ॥ २७ ॥
ITRANS:
nābhir nabhas te śvasanaṁ nabhasvānsūryaś ca cakṣūṁṣi jalaṁ sma retaḥparāvarātmāśrayaṇaṁ tavātmāsomo mano dyaur bhagavan śiras te
Translation:
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.
