Guru-gaurāṅga: "Translation: The Supreme occupation, dharma, for all humanity is that by which men can attain to loving devotional service unto the transcendent Lord. Such devotional service must be unmotivated and uninterrupted in order to completely satisfy the self."
Prabhupāda: Yes. That is self-satisfaction. Yayātmā suprasīdati. Ahaituky apratihatā. So the bhakti cult is open for everyone. Ahaituky apratihatā.
