The process, as you have already known, the process is chanting the holy name of God: Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. Now this is recommended in the Vedas that, "In this age people are so much fallen that they cannot realize God by the prescribed method, therefore the best chance for them is to chant this holy name of God." That is recommended in the Vedas.
You can chant . . . if you know any other name of God, you can chant also, because there is no difference between the different names of God. And each name, holy name, is invested with all powers of God. Lord Caitanya says that each and every name, holy name of God, is nondifferent from the Supreme Lord. Therefore all the powers, all the energies that God has, it is also there in His holy name. In the absolute platform there is no such difference, as in this relative world there is difference between the name and the person whose name we are chanting. As such, there is no difference between the holy name of God and God. And Caitanya Mahāprabhu says there is no hard and fast rules and regulations for this chanting.
So you can chant the holy name of God anywhere, everywhere, and wherever it is possible. So suppose you are walking on the street or passing on the buses, but if you chant the holy name of God, especially Hare Kṛṣṇa, Hare Kṛṣṇa, you will get much benefit without any loss of your money or without any hampering of your business.
We therefore request and recommend that so long we live, we may chant the holy name of God: Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. We don't charge anything for giving you this name. It is open to everyone. You can take it and make an experiment. By chanting, you will feel how much you are advancing in spiritual knowledge.
This is the shortcut way of understanding God realization. But if you don't believe in the simple method, if you want to understand this philosophy through science and philosophy, we have got books, about one dozen books, four hundred pages each, to explain this science of chanting Hare Kṛṣṇa mantra. We have got our magazine, Back to Godhead, and our books, Kṛṣṇa book, Nectar of Devotion, Bhagavad-gītā, Śrīmad-Bhāgavatam. So many books we have got.
So those who are very much serious . . . and everyone should be serious, because if we miss this opportunity, then after death we do not know what is going to happen. I may have a human form of body or we may have a body of the animals or of a tree. That we do not know. But if we chant Hare Kṛṣṇa mantra and become advanced in Kṛṣṇa consciousness, at least next life again human form of body is guaranteed.
