The world stands in no need of any reformer. The world has a very competent person guiding its minutest happenings. The person who finds that there is scope for reform of the world, himself stands in need of reform. The world goes on in its own perfect way. No person can deflect it but the breath of a hair from the course chalked out by Providence. When we perceive any change being actually effected in the course of events of this world by the agency of a particular individual, we also know that the agent possess no real power at any stage. The agent finds himself driven forward by a force belonging to a different category from himself.
The course of the world does not require to be changed by the activity of any person. What is necessary is to change our outlook on this very world. This was done for the contemporary generation by the mercy of Lord Caitanya. It could be known only by the recipients of His mercy.
The scriptures declare that it is only necessary to listen with an open mind to the name of Krishna from the lips of a bona-fide devotee. As soon as Krishna enters the listening ear, He clears up the vision of the listener so that he no longer has any ambition of ever acting the part of a reformer of
any person, because he finds that nobody is left without the very highest guidance. It is therefore his own reform, by the grace of God, whose Supreme necessity and nature he is increasingly able to realize by the eternally continuing mercy of the Supreme Lord.
