So Vedic literature informs us that the meditation process was possible to be successful in the age which is called Satya-yuga, when people used to live for hundred thousands of years. The next age, Tretā-yuga, the self-realization process is offering sacrifices. And the next age, Dvāpara-yuga, when people used to live for one thousand years, the recommendation is temple worship or church worship, like that. But in this age the recommendation is kalau tad dhari-kīrtanāt. Kalau. Kalau means in this age, when duration of life is very short. Actually, although officially the age is calculated that we can live for one hundred years, but nobody goes up to that limit. Most utterly, very old man means eighty years or eighty-five years. That's all. But gradually, the duration of age in this period will decrease so much so that it is stated that if a man lives for twenty to thirty years, he'll be considered a very old man. That is also predicted. So we are gradually declining in our strength, in our duration of life, in our memory, in our merciful activities, so many things. So in this age there is no time for meditation, there is no money for offering great sacrifices, neither people are very much interested in temple worship or church worship. Therefore, wherever you remain, you can simply chant this mahā-mantra—Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. That is the recommendation of Vedic literature. Kalau tad dhari-kīrtanāt. Simply by chanting these sixteen names, Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare... There are actually three words only—Hare, Kṛṣṇa, Rāma—but they are set up very nicely.
So our Kṛṣṇa consciousness movement is just according to the direction of authoritative Vedic literature, and we are distributing this knowledge without any charge. We don't say there is any secrecy. It is wide open. Open secret. Anyone can take up these sixteen names and chant. And test it, chanting, say, for a week, and see the result. See the result, how you are spiritually realizing yours. Ceto-darpaṇa-mārjanam (CC Antya 20.12). If you go on chanting this Hare Kṛṣṇa mantra, then first installment of your gain will be that you will understand that you are not this body, you are spirit soul, which takes at least many years to understand, that "I am not this body." Everybody... You ask anybody, "What you are?" He will say, "I am this, sir, this and that. I am American. I am this body. I am that body." But nobody knows that he is not this body. But if you chant this Hare Kṛṣṇa mantra, the first installment of your gain will be that you will realize yourself, ahaṁ brahmāsmi: "I am not this body, but I am spirit soul. I am part and parcel of the Supreme Lord." And as soon as you come to this platform of understanding, then the next stage will be you will (be) jolly. Brahma-bhūtaḥ prasannātmā na śocati na kāṅkṣati (BG 18.54). Brahma-bhūta (SB 4.30.20) means self-realization, when one understands that "I am not this body." Due to this body, all sufferings are there. That we do not understand. We simply go to the physician. Although we know the body is the temple of all kinds of diseases, but we do not know how to get out of this material body. But there is possibility.
