“Rupa Gosvami has stated that five kinds of devotional activities - namely, residing in Mathura, worshiping the Deity of the Lord, reciting Shrimad-Bhagavatam, serving a devotee, and chanting the Hare Krishna mantra - are so potent that a small attachment for any one of these five items can arouse devotional ecstasy even in a neophyte.” (The Nectar of Devotion, Ch 13)
