Our Kṛṣṇa consciousness movement is just to awake people to their rightful position, which is called Kṛṣṇa consciousness. Kṛṣṇa consciousness means to understand how he is related with Kṛṣṇa. When we speak of Kṛṣṇa, "Kṛṣṇa" means God. The word Kṛṣṇa, Sanskrit word, means all-attractive. So without God, nobody can be all-attractive, all-powerful, all-opulent. So this Kṛṣṇa consciousness movement is directed to awake people to the rightful position of his spiritual existence, the, I mean, process. Of course, there are many different kinds of processes recommended in the Vedic literature. Just like some of you, or any one of you, know that one process is very important process which is called meditation, dhyāna. So that dhyāna, that is also mentioned, kṛte yad dhyāyato viṣṇum (SB 12.3.52). This meditation process was possible to be executed in the age when people were very pious and very honest and the duration of life was very long. That is called Golden Age, or Satya-yuga. According to Sanskrit word, it is called Satya-yuga. This meditation process was possible to be executed in the Satya-yuga, Satya millennium.
Then the next millennium, Tretā-yuga. There is a great description of these yugas. In the Satya-yuga, people used to live for one hundred thousands of years. People used to live. It is not that . . . that according to the modern anthropologists, they say that ten thousand years ago there was no human being. These are the not the Vedic version.
We do not accept this version, because we find that there was age, which is called Satya-yuga, when people used to live for one hundred thousands of years. The next age, Tretā-yuga, when people used to live for ten thousands of years. Then next age is called Dvāpara-yuga, when people used to live for one thousand years. Now it is called Kali-yuga, when people can live, utmost, one hundred years. These are the calculation of different ages.
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 one 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. (SB 12.3.52). 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.
