All the dirty things from your heart will be cleansed simply by chanting. You chant. There is no expenditure; there is no loss. But as we are chanting, if you kindly chant... You just do it for one week, and you see how much you progress in spiritual knowledge. We are getting many students. Simply by chanting, they are understanding the whole philosophy. They are giving up their bad habits, they are becoming purified, so many things.

If you have to bother, if you have to tax your brain, just do it for Kṛṣṇa, for God. That is proper utilization of your time. Bread is already there. There is no scarcity of bread in the kingdom of God.

This institution, Kṛṣṇa consciousness movement, is giving chance to everyone. And we are opening centers all over the world for this purpose, that "You come, chant Hare Kṛṣṇa mantra, hear about Kṛṣṇa, Bhāgavatam, Bhagavad-gītā, and whatever you can do, just do it for Kṛṣṇa." Then your life is successful.
Thank you very much.
Śrīmad-Bhāgavatam 1.8.30 -- October 10, 1974, Māyāpur
