Laksmi Nrsimhadev: Being a part of the Radha-Damodar traveling sankirtan party we often got to meet Srila Prabhupada. This time Tamal Krishna Maharaj wanted to give him a donation from the party of $100,000 in cash. He had a stack of $1,000 bills, which I don’t think they make anymore, and there were supposedly 100 of them. Tamal said, “Srila Prabhupada, your disciples on Radha-Damodar traveling sankirtan party would like to give you this donation of $100,000.” Srila Prabhupada said, “Oh?” Then Tamal Krishna Maharaj gave Srila Prabhupada the stack of bills. Srila Prabhupada took the stack of bills and like a card dealer put them close to his ear and he fanned them. It made a “frrrrr” sound. Prabhupada looked up at Tamal and said, “100,000?” Tamal got this look of panic on his face because before meeting with Srila Prabhupada he realized he had only $99,000. So he had a devotee run to the bank and change another thousand dollars into a $1,000 bill but he forgot to put it into the stack. After Srila Prabhupada did that little “frrrrr” sound of fanning the stack of bills, Tamal remembered the last minute bank transaction and pulled out the other $1,000 bill from his pocket and gave it to Srila Prabhupada.
