The word tan-mayam in this verse is significant. One who is purified by worshiping the Deity form of the Lord can understand that he, the worshiper, is an eternal servant of the Lord and is qualitatively one with the Lord, being like a tiny spark of the original fire, the Personality of Godhead. Srila Madhvacarya has stated in this regard,
vishnor bhrityo 'ham ity eva
sada syad bhagavan-mayah
naivaham vishnur asmiti
vishnuh sarvesvaro hy ajah
"One should think, 'I am an eternal servant of Vishnu, and therefore, because I am His eternal part and parcel, I am eternally one with Him. But I am not Vishnu Himself, because Vishnu is the supreme controller of everything.' "
The basic principle of Deity worship is that one must understand oneself to be an eternal servant of the Supreme Lord. One who is addicted to sexual gratification, foolishly identifying himself with the external material body, cannot change his conception of himself from that of an enjoyer to that of the enjoyed. Such a person interprets the word tan-mayam to mean that the worshiper is himself also the worshipable object. Sri Jiva Gosvami Prabhupada has written in his Durga-sangamani, his commentary on Sri Rupa Gosvami Prabhu's Bhakti-rasamrita-sindhu, that ahangrahopasana, or the process of worshiping oneself as the Supreme, is a gross misidentification of one's own self with the Supreme, who is actually one's eternal shelter. The six Gosvamis have repeatedly clarified this point. But unintelligent persons within the prakrita-sahajiya community become influenced by the bogus ideas of the Mayavadi philosophers and thus display the deluded misconception that the worshiper becomes the supreme shelter. Such a hallucination is an aparadha, an offense against the Lord. Therefore the word tan-maya in this verse should not be offensively understood to mean that the worshiper becomes equal to his eternal worshipable object.
