The Supreme Personality of Godhead is situated in pure goodness [śuddha-sattva], and therefore He is eka-varṇa — the oṁkāra [praṇava]. Because the Lord is beyond the cosmic manifestation, which is considered to be darkness, He is not visible to material eyes. Nonetheless, He is not separated from us by time or space, but is present everywhere. Seated on His carrier, Garuḍa, He is worshiped by means of mystical yogic power by those who have achieved freedom from agitation. Let us all offer our respectful obeisances unto Him.
