“ ‘The spiritually powerful message of Godhead can be properly discussed only in a society of devotees, and it is greatly pleasing to hear in that association. If one hears from devotees, the way of transcendental experience quickly opens, and gradually one attains firm faith that in due course develops into attraction and devotion.’
This is a quotation from Śrīmad-Bhāgavatam (3.25.25).
