When Kṛṣṇa was born . . . of course, He is pure. He is God. But the social and the scriptural rules and regulations were followed. So when a child is born the astrologer is called. Still that system is followed. But due to this Kali-yuga the astrologer has also become a false, and this has become a formality. Somebody is following; somebody is not following.
So as soon as a child is born . . . you will find Mahārāja Parīkṣit, as soon as he was born, his grandfather, Mahārāja Yudhiṣṭhira, called for astrologer. This is called jāta-karma. Just after the child is born, this astrologer will come and he will see the moment, the astronomical situation, and make a horoscope, and then immediately his future activities and everything will be clearly made, that "This child is born at such-and-such moment. He will be like this and this." And that will be . . .
You will be surprised. . . not surprised; this is calculation. In my horoscope it is written there, "At the age of seventy years he will go across the sea." It is written there. Yes. And there are so many things still. So this astrologer was so accurate. I have got that horoscope. Not here. If some day I shall, then will show. It is clearly written there that "This time he will go across the sea." Just see. The circumstances became so that I have come. So astrology is so nice.
So when Kṛṣṇa was born, the same principle was followed. Astrologer was called for, and there were good astrologers. And the great astrologer, a famous astrologer who came to see Kṛṣṇa's birth affair, he was Garga Muni. His name was Garga Muni. Yes. So that Garga Muni, by astrology, said to Kṛṣṇa's father Nanda Mahārāja, "This boy, this child who is born as your son, He had three colors before." Āsan varṇās trayo hy asya (CC Madhya 20.331): "This child had three colors before. I see."
Just see the astrology. From astrology he says that, "He had three colors before." That means God. "He had three colors before." Gṛhṇato 'nuyugaṁ tanūḥ: "According to the age, according to the millennium, He had three other colors." Śuklo raktas tathā pīta idānīṁ kṛṣṇatāṁ gataḥ: "And He had that white color and red color and yellow color." Idānīm: "Just now, He has assumed this black color." So this was the astronomical calculation of Kṛṣṇa's birth. Satya-yuge dharma-dhyāna karāya 'śukla'-mūrti dhari' (CC Madhya 20.334).
