The best way a devotee can show mercy is to distribute the message of Godhead throughout society. In this way, he will always be acting for the enlightenment of human society. A devotee is one who distributes Krishna’s mercy. We often say that the spiritual master is merciful because he distributes the Lord’s mercy just as a rain-cloud distributes water from the ocean. A rain cloud does not carry its own water, but takes water from the ocean. In the same way, a devotee carries the Lord’s mercy and shares it with others.
