Although the ingredients of sacrificial performance — the place, time, particular paraphernalia, mantras, rituals, priests, fires, demigods, performer, offering and the as yet unseen beneficial results — are all simply aspects of His opulences, the brāhmaṇas saw Lord Kṛṣṇa as an ordinary human because of their perverted intelligence. They failed to recognize that He is the Supreme Absolute Truth, the directly manifest Personality of Godhead, whom the material senses cannot ordinarily perceive. Thus bewildered by their false identification with the mortal body, they did not show Him proper respect.
