(Prabhupada - Master at whose feet all other masters sit - San Francisco Rathayatra, 1974.)
"We are servant of servant. That is Caitanya Mahaprabhu's instruction, gopi-bhartuh pada-kamalayor dasa-dasanudasah (CC Madhya 13.80). The more you become servant of the servant, the more you are perfect. And if you all of a sudden want to become master, then you go to hell. That's all. Don't do that. This is the teaching of Sri Caitanya Mahaprabhu. If you go through the servant, servant, servant, then you are advanced. And if you think that you have now become master, then you are going to hell. This is the process. Dasa-dasa-dasanudasah. Caitanya Mahaprabhu said. So servant, servant, servant, a hundred times servant now, that means he is advanced. He is advanced. And one who is becoming directly master, then he is in the hell."
