When I was in Bombay, Prabhupada was told, "Prabhupada, devotees don't come to mangal arati." Prabhupada said, "Everyone must come to mangal arati." Then someone proposed that devotees who don't attend mangal arati must fast.
Prabhupada said, "Yes." Someone wrote a paper to that effect, and Prabhupada signed it. Prabhupada was very careful and wanted us to come to a certain standard.
