adhyāsitaḥ sakala-loka-namaskṛtaṁ yat
tepe tapo bahu-savo ’varurutsamānas
tasmai namo bhagavate ’dhimakhāya tubhyam
Brahmā is the greatest personality in the universe because he has the longest duration of life. He is the most respectable personality because of his penance, influence, prestige, etc., and still he has to offer his respectful obeisances unto the Lord. Therefore, it is incumbent upon all others, who are far, far below the standard of Brahmā, to do as he did and offer respects as a matter of duty.
