Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 10-11
Sanskrit:
देश: काल: पृथग्द्रव्यं मन्त्रतन्त्रर्त्विजोऽग्नय: ।देवता यजमानश्च क्रतुर्धर्मश्च यन्मय: ॥ १० ॥तं ब्रह्म परमं साक्षाद् भगवन्तमधोक्षजम् ।मनुष्यदृष्ट्या दुष्प्रज्ञा मर्त्यात्मानो न मेनिरे ॥ ११ ॥
ITRANS:
deśaḥ kālaḥ pṛthag dravyaṁmantra-tantrartvijo ’gnayaḥdevatā yajamānaś cakratur dharmaś ca yan-mayaḥ
Translation:
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.
Purport:
The ritualistic brāhmaṇas could not understand why the sacrificial food should be offered to Lord Kṛṣṇa, whom they considered an ordinary human being. Just as a person with rose-colored glasses sees the entire world as rose-colored, a conditioned soul with mundane vision sees even God Himself as mundane and thus loses the opportunity to go back home, back to Godhead.
