God Is Present In His Sound Vibration - Prabhupada 0887
670121 - Lecture CC Madhya 25.29 - San Francisco
So one of the chief disciple of Prakāśānanda Sarasvatī, he very much appreciated Caitanya Mahāprabhu's presentation of Vedānta-sūtra and excellent presentation of harer nāma harer nāma harer nāma eva kevalam (CC Adi 17.21). That "In this age there is no other alternative for self-realization than chanting this Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare / Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare," harer nāma, the holy name of God. So considering the fallen age at the present moment, God is so merciful and kind that He presents Himself as sound, sound vibration, which everyone can produce by his tongue and can hear, and God is present there.
