Pariksit Maharaja was informed by Sukadeva Gosvami, "My dear King, I have described about the faulty nature of this age." Kaler dosa-nidhi. Dosa-nidhi means an ocean of faults. "But there is one good opportunity." Kaler dosa-nidhe rajann asti hy eko mahan gunah. "There is one good quality." What is that? Kirtanad eva krsnasya mukta-sangah param vrajet [SB 12.3.51]. Simply by chanting Hare Krsna mantra, one can become free from all this contamination and he can go back to home, back to Godhead." This is another advantage of Kali-yuga. In other yuga one has to undergo so much severe austerity, penances. Then one can realize. But in this age the things have been made easy. That is also mercy of Krsna because these people are so much, disturbed and fallen, downtrodden, they cannot undergo very severe austerity. Simply chant.
