Srila Prabhupada and Lord Venkateshwara.
Yadubara das: Srila Prabhupada stayed in Tirupati for three days, and the highlight of that trip was a special early morning darshan at 2:00 a.m. I remember it was just a very mystical atmosphere, entering the Deity room by torchlight and then coming in front of Lord Venkateshwara and the pujari waving the ghee lamp to illuminate His form. It was wonderful to see Srila Prabhupada gaze in reverence upon his Lord.
