Every worshipper must remember that Krsna is personally present. He is simply kindly presenting Himself before us in a way so that we can handle Him. That is His mercy, otherwise He is unapproachable.
atah sri-krsna-namadi na bhaved grahyam indriyaih
sevon mukhe hi jivadau svayam eva sphuraty adah
[Brs. 1.2.234]
"No one can understand the transcendental nature of the name, form, quality and pastimes of Sri Krsna through his materially contaminated senses. Only when one becomes spiritually saturated by transcendental service to the Lord are the transcendental name, form, quality and pastimes of the Lord revealed to him.'' (Padma Purana).
