Gaur Hari: One time in Mayapur it was hot and I was nodding out, sleeping during one of Prabhupada's classes. All around him there must have been fifteen or twenty sannyasis, and you could see all their dandas going down and up as they were also nodding out. But Prabhupada pointed to me and said, "Wake up!" All of a sudden all the dandas straightened up. I took it as Prabhupada using me to wake everybody up.
