Five thousand years ago, during the time of Mahārāja Parīkṣit. Gradually, people are degrading, only on these principles: illicit sex, animal slaughter, intoxication and gambling. These are the four pillars of the platform of Kali.
So Mahārāja Parīkṣit when... That means five thousand years ago, all over the world these things were unknown. You won't find in history these things. So as king, he has to punish the debauchers, the rogues, the thieves. So immediately he become alert. It says, niśamya vārtām anatipriyām. When he got news, so although no enemy is there attacking, but Kali is attacking. Kali's attacking. Kaliṁ praviṣṭaṁ nija-cakravartite. Praviṣṭam. Kali has already entered in his own jurisdiction, cakravartī. The cakra, cakra means circle, and vartī means remaining in the center. So a king is supposed... A king or a spiritual master or the head is supposed to be the center of a circle. So his kingdom is supposed to be the circle. He is the center. Nija-cakravartite, within his jurisdiction, within the circle. Kaliṁ praviṣṭam, niśamya. As soon as he heard, he became alert to punish.
That is responsible king.
