What is more public welfare than Krishna Consciousness? To awaken everyone's original consciousness is the best public welfare in the whole world.
Now people are seeing how genuine our movement is, they are coming forward to offer us so many places. We simply have to maintain our strict principles, keeping ourselves pure, Otherwise, there are so many bogus institutions doing business in the name of God and simply cheating the people. We have to be careful not to degenerate like these others. Our strength depends upon regular chanting the required 16 rounds and rigidly adhering to the regulative principles.
