Mahārāja Parīkṣit, when he saw that a black man was going to kill one cow, immediately he took his sword: "Who are you? I shall kill you immediately." That was king's stricture. So the Kali was ordered to get out of his kingdom. He begged of his life, "Sir, you are going to kill me. But it is my time. I have now come, and it is my business, cow-killing. So what can I do? This is my business." So Mahārāja Parīkṣit understood that now the Kali-yuga is coming. So it is his business. So "I am as king. How can I stop his business?"
That is also another problem. One must be occupied, one must be engaged in his business. Therefore, he asked him to go to these places. Where? In the slaughterhouse, in the brothel for illicit sex, and slaughterhouse, and in the drunkard den for intoxication, and gambling place. So Kali was in difficulty to find out a place like that in that time. He could not find. Therefore there was conspiracy to kill the king so that Kali can enter.
So these are the principles. This is called human society. Varnāśramācaravatā puruṣeṇa paraḥ pumān (CC Madhya 8.58). In human society, viṣṇur ārādhyate, the Lord is worshiped. But ne te viduḥ svārtha-gatiṁ hi viṣṇuḥ. At the present moment, these rascals, they do not know. Andhā yathāndair upanīyamānāḥ. And the so-called leaders, they are blind themselves, and they are trying to lead other blind men. This is the social position. Therefore there is no more hope of reviving the Vedic culture. But by the grace of Caitanya Mahāprabhu, ceto darpana mārjanam . . . (CC Antya 20.12) The Vedic culture means to cleanse the heart and make him perfect. Brahma-bhūtaḥ, perfectly spiritualized. That is Vedic culture. Vedaiś ca sarvair aham eva vedyaḥ (BG 15.15). To know the Supreme Lord, that is Vedic culture. Now everything is topsy-turvied.
