If you associate with any one of them, either God personally or with His name or with His form or with His quality or with His paraphernalia, immediately you become in contact with God. This is the science. This is not fiction; this is science. Because if you accept God as absolute, there cannot be difference between God and His name and His form.
So this is science. You'll realize as you make progress. You'll realize. Just like these boys, they're chanting Hare Kṛṣṇa mantra, they are realizing; otherwise I've not bribed them. They're mad after Hare Kṛṣṇa mantra. It is not due to my bribing them. They're actually realizing that they are in touch with Kṛṣṇa. So anyone can do that. Caitanya Mahāprabhu says, therefore, that there are many thousands of names of God. Although we say that the only perfect name is "Kṛṣṇa," but if you think, "No, we have got another name," that's all right. But it must be the name of God. It must be full with the conception of God.
If you have got, you can chant that name also. There is no hindrance. Nāmnām akāri. Because every name being identical with God, every name of God is as powerful as God. As powerful, because identical. Identical. Therefore every name has got the same power and potency as the Supreme Person, God, has got. Nāmnām akāri bahudhā nija sarva śaktis. Nija sarva śaktis: all potencies are there. Tatrārpitā. There is; it is already endowed with all the potencies.
