How ISKCON guru system works
Before you become officially initiated in ISKCON, you have to figure this out:

TRANSLATION: Senior devotees have approved authorisation process that authorized person is approved as guru because certain approvers are seniors. But, having been approved by approvers doesnât signify that approved guru is actually approved. Rather, approval doesnât mean much, it is just an imagined process, since Prabhupada never instructed anybody to approve gurus.
But, we will approve anyway, but approval doesnât mean much, we approve, but if approved guru becomes a sannyasi with girlfriend, that is your fault that you selected him as your guru. Why did you do that? Because he was approved? Since approved guru is not actually approved, we donât feel any urge to disapprove Sacinandana Swami and his girlfriend from the guru list. After all, it is your fault that you accepted approval done by approvers as something approved.â
