Bhāgavata: ...celebrate.
Prabhupāda: The celebration is you have to fast day and night and four times offer worship to the Lord Śiva.
Dr. Patel: And drink bhang also.
Prabhupāda: No, no, that is not recommended. But they can do... They do all now...
Bhāgavata: So we should observe this festival, Śrīla Prabhupāda?
Prabhupāda: Not necessarily.
Bhāgavata: Not necessary.
