"Communion with the Lord by transmission of the transcendental sound is nondifferent from the whole spirit Lord Śrī Kṛṣṇa. It is a completely perfect method for approaching the Lord. By such pure contact with the Lord, without offense of material conceptions (numbering ten), the devotee can rise above the material plane to understand the inner meaning of the Vedic literatures, including the Lord's existence in the transcendental realm. The Lord reveals His identity gradually to one who has unflinching faith, both in the spiritual master and in the Lord. After this, the devotee is endowed with mystic opulences, which are eight in number. And above all, the devotee is accepted in the confidential entourage of the Lord and is entrusted with specific service of the Lord through the agency of the spiritual master. A pure devotee is more interested in serving the Lord than in showing an exhibition of the mystic powers dormant in him."
(Śrīmad-Bhāgavatam 1.5.39, Purport)
