Kṛṣṇa's pastimes, appearance and dis . . . disappearance, is continuous and eternal. There is no stoppage. Lord Caitanya says, bujhite nā pāre līlā kemane 'nitya' haya. Ordinary persons, common men, cannot understand how kṛṣṇa-līlā, Kṛṣṇa's appearance and disappearance, can be eternal. Generally, we think that Kṛṣṇa appeared five thousand years before; now He's no longer. So either He's dead or gone. Just like ordinary man takes his birth and stay here for some time, and then he goes away—no more, no trace of that particular man's activities. He's lost in the whirlpool of this material ocean.
Neither exactly in a similar body that particular living entity will again come back. Once. This form which you have got, material form, it is just like a bubble in the ocean. It is formed somehow or other according to our past actions and reactions, and it will stay for hundred years at most. Then it will disappear. And there will be no trace where that particular individual soul has gone.
Of course, there is account in the books of Supreme Personality of Godhead. Vedāhaṁ samatītāni (BG 7.26). He says, "I know everything." And He's always constant companion. As Supersoul of the individual soul, He knows. But we, the persons of a particular person's relatives, father, mother, brother, all these things—who knows? Nobody can give information.
But Kṛṣṇa's appearance and disappearance is not like that, because He's not different from His body. We are, in our conditioned stage, we are different from our body. But Kṛṣṇa and Kṛṣṇa's body is the same thing. This is to be understood. Sac-cid-ānanda-vigraha (Bs. 5.1).
