Saintly persons are not interested in political matters, yet they are always thinking of the welfare of the people in general. Consequently they sometimes have to come down to the political field and take steps to correct the misguided government or royalty. However, in Kali-yuga, saintly persons are not as powerful as they previously were. They used to be able to burn any sinful man to ashes by virtue of their spiritual prowess. Now saintly persons have no such power due to the influence of the Age of Kali. Indeed, the brahmanas do not even have the power to perform sacrifices in which animals are put into a fire to attain a new life. Under these circumstances, instead of actively taking part in politics, saintly persons should engage in chanting the maha-mantra, Hare Krsna. By the grace of Lord Caitanya, by simply chanting this Hare Krsna maha-mantra, the general populace can derive all benefits without political implications.
