That is up to you to judge

Devotee: ...one is sufficient to ask is that are Siddha-svarūpānanda Gosvāmī and Tuṣṭa-kṛṣṇa Mahārāja and their followers more advanced in their understanding of Kṛṣṇa and the spiritual master than the other devotees in ISKCON; and secondly, are they, have they advanced beyond following the rules and regulations of ISKCON?

Prabhupāda: That is up to you to judge—by the result. If they are actually advanced, why they should leave this company of ISKCON? Therefore, I know they're very good souls. They might have done some mistake out of misunderstanding, but you invite them to come back again and take their position. It is not very good sign that they have left. They'll never be happy. That's a fact. (pause)

Hare Kṛṣṇa. (end)
