Just like Jesus Christ. He is being crucified, and still he is merciful: "God, these people do not know what they are doing. Please excuse them." This is sadhu. He is personally being disturbed by the demons, but still, he is merciful to the general people. They are suffering for want of Krsna consciousness. So even up to the point of death, he is trying to preach Krsna consciousness. "Let the people be benefited. Eh, what is this material body? Even if I am killed, I am not killed. This body is killed, that's all." This is sadhu. Titiksavah karunikah. In one side he is tolerant, and other side, merciful.
