SB 1.18.5
tavat kalir na prabhavet
pravisto ’piha sarvatah
yavad iso mahan urvyam
abhimanyava eka-rat
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
As long as the great, powerful son of Abhimanyu remains the Emperor of the world, there is no chance that the personality of Kali will flourish.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
As we have already explained, the personality of Kali had entered the jurisdiction of this earth long ago, and he was looking for an opportunity to spread his influence all over the world. But he could not do so satisfactorily due to the presence of Maharaja Pariksit. That is the way of good government. The disturbing elements like the personality of Kali will always try to extend their nefarious activities, but it is the duty of the able state to check them by all means. Although Maharaja Pariksit allotted places for the personality of Kali, at the same time he gave no chance for the citizens to be swayed by the personality of Kali.
