SP accepts prasadam only after offering it to his Guru first

He would always offer everything first to his gurudeva and then he would take prasadam. Once I witnessed an incident when the Radha Damodara pujari put a garland from the altar around his neck. He said, 'No, no, do not put this on my head. I shall offer it first to my guruji.' I took note that he went and offered it to his gurudeva's photograph in his room and then only after that would he take it on his head.
