TRANSLATION

"By this mantra, the people worship Lord Krsna in the Dvapara-yuga. In the Kali-yuga the occupational duty of the people is to chant congregationally the holy name of Krsna.

As stated in Srimad-Bhagavatam (12.3.51):

kaler dosa-nidhe rajann
asti hy eko mahan gunah
kirtanad eva krsnasya
mukta-bandhah param vrajet

In Kali-yuga one worships Lord Krsna by chanting Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare. To propagate this movement, Lord Krsna personally appeared as Lord Caitanya Mahaprabhu. That is described in the following verse.
