In this age, the śāstric injunction . . . that means the injunction of the authorized scripture is that kṛte yad dhyāyato viṣṇum. In the golden age, when people used to live for 100,000's of years, meditation was possible. Because we understand Vālmīki Muni, he got perfection by meditation after meditating 60,000's of years.
And similarly, Kardama Muni, he got perfection by meditation after 10,000's of years' meditation. So meditation process is difficult process, and it is not possible in this age. This is the injunction of the śāstra. Simply we can waste our time by so-called meditation, but real meditation is not achievable at the present age.
Therefore the prescription is kṛte yad dhyāyato viṣṇum tretāyāṁ yajato makhaiḥ (SB 12.3.52). In the first millennium, meditation was possible. In the second millennium, sacrifice . . . big, big yajña, or sacrifice, was performed by people. And the third millennium, temple worship. And in the fourth millennium, kalau tad dhari-kīrtanāt: in this age of Kali, simply by chanting Hare Kṛṣṇa you can attain the perfection. So these are the prescription. We have to follow.
So our policy, those who are serious about Kṛṣṇa consciousness, they should not waste their time for sense gratification. And because the body is there, we are not free from the body, there are demands of the senses. So that should be controlled. That is the process in every line of action, either you meditate or you perform sacrifices, do anything. The real process is to control the senses. So try to control the senses as far as possible and utilize your time for advancing Kṛṣṇa consciousness. And the process is very simple—simply chanting Hare Kṛṣṇa, Hare Kṛṣṇa.
So make your life regulated. There is no denial. It is not that you cannot eat or you cannot sleep or you cannot have sex life or you cannot defend yourself. Do all these things according to the rules and regulation. But don't waste your time for artificial increment of sense gratification. Don't do that. You require to eat to maintain your body and soul together—you eat. Yuktāhāra-vihārasya yogo bhavati (BG 6.17) siddhi-daḥ. You don't require to eat less. Suppose you can eat one pound. The Kṛṣṇa conscious prescription does not say, You simply eat one ounce. No. You eat one pound—but don't eat more.
Similarly, you have to sleep. All right, make your shelter, apartment, nicely so that you can comfortably sleep. Defense, yes, you defend your country, you defend your home nicely. Sex life, yes, you have sex life, but not in the unrestricted way. Limited with married wife or married husband and comfortably and very gentlemanly.
So these are prescriptions are there. There is no denial. But make it systematic. But the balance of your life . . . don't spoil your life simply for sense gratification or so-called advancement of material civilization. You should utilize your time how to make advancement in Kṛṣṇa consciousness. That is the sum and substance of Prahlāda Mahārāja's instruction to his class fellows who were born of atheistic family.
