Here Lord Sivas excellent character is described. In spite of the cursing and countercursing between the parties of Daksa and Siva, because he is the greatest Vaisnava he was so sober that he did not say anything. A Vaisnava is always tolerant, and Lord Siva is considered the topmost Vaisnava, so his character, as shown in this scene, is excellent. He became morose because he knew that these people, both his men and Daksas, were unnecessarily cursing and countercursing one another, without any interest in spiritual life. From his point of view, he did not see anyone as lower or higher, because he is a Vaisnava. As stated in Bhagavad-gita (5.18), panditah sama-darsinah: one who is perfectly learned does not see anyone as lesser or greater, because he sees everyone from the spiritual platform. Thus the only alternative left to Lord Siva was to leave in order to stop his follower, Nandisvara, as well as Bhrgu Muni, from cursing and countercursing in that way.
