The mother cried, requested... He forced the mother, Prahlāda's mother, "Give your son this poison." So she begged so much, but he was a rascal demon. "No, you must give." So the mother knew, the son knew that the rascal father is giving this poison. What can he do, a small child? "All right, let me drink." Guruṇāpi duḥkhena na vicālyate. He is not agitating. "All right, if Kṛṣṇa likes, I will live." This is the position of sādhu. He is not disturbed. Titikṣavaḥ. In all circumstances, he is tolerant. That is sādhu. Sādhu does not become disturbed. Titikṣavaḥ. At the same time, kāruṇikāḥ. He is himself disturbed, but he is merciful to others.
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 sādhu. He is personally being disturbed by the demons, but still, he is merciful to the general people. They are suffering for want of Kṛṣṇa consciousness.
