Reporter: Is this singing essential to the sustenance of your faith?
Prabhupāda: This singing is the process for clearing the dust accumulated on the heart. Our relationship with God is eternal. It cannot be broken. But due to the contact of māyā we are trying to forget Him. But if we chant this holy name of God, Hare Kṛṣṇa, then māyā will not act, and we shall very quickly understand what is our relationship with God. That is the process. Ceto-darpaṇa-mārjanam (CC Antya 20.12, Śikṣāṣṭaka 1). The Sanskrit word is "cleansing the dirty heart." The dirty heart.
In the Bhagavad-gītā it is said, na māṁ duṣkṛtino mūḍhāḥ prapadyante narādhamāḥ (BG 7.15). Those who are miscreants, rascals, and lowest of the mankind, and taken all knowledge, and atheistic class of men, they do not know what is God. Others, those who are virtuous, those who are inquisitive, those who are wise, they will try, and they will understand what is God.
So my appeal to you is that you try to understand this movement, Kṛṣṇa consciousness movement. It is not a bogus movement. It is scientific, authorized. Any scientist, any philosopher, any logician may come and we shall prove that there is God and we have got eternal relationship with God.
So if you want to (be) happy, then you must take to this Kṛṣṇa consciousness movement. Otherwise the human race is doomed. Harāv abhaktasya kuto mahad-guṇā (SB 5.18.12). Anyone who has no God consciousness, he has no qualification. However academically he may be very rich, he has no qualification. Manorathena asato dhāvato bahiḥ. His only qualification is mental concoction. Mental concoction. That's all. He has no other qualification. So we reject all these nonsense. We simply accept a sincere soul who wants to dedicate his life for God's service.
So it is not easy thing. These boys and girls who are following me, they are very elevated. They are not ordinary boys and girls. They have taken to Kṛṣṇa consciousness. Their quality is greater than any mundane erudite scholar. It is a challenge. Yasyāsti bhaktir bhagavaty akiñcanā sarvair guṇais tatra samāsate surāḥ (SB 5.18.12).
Anyone who has developed Kṛṣṇa consciousness, love of God, all good qualities will automatically develop in him. All good qualities. Test any of our students, how they are good, how they are advanced. Test it. Bring anyone in this world and test any one of our boys, you'll find how much difference there is in their character, in their feeling, in their consciousness.
