The sage Maitreya said: When such cursing and countercursing was going on between Lord Śiva's followers and the parties of Dakṣa and Bhṛgu, Lord Śiva became very morose. Not saying anything, he left the arena of the sacrifice, followed by his disciples.
Here Lord Śiva's excellent character is described. In spite of the cursing and countercursing between the parties of Dakṣa and Śiva, because he is the greatest Vaiṣṇava he was so sober that he did not say anything. A Vaiṣṇava is always tolerant, and Lord Śiva is considered the topmost Vaiṣṇava, so his character, as shown in this scene, is excellent. He became morose because he knew that these people, both his men and Dakṣa's, 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 Vaiṣṇava. As stated in Bhagavad-gītā (5.18), paṇḍitāḥ sama-darśinaḥ: 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 Śiva was to leave in order to stop his follower, Nandīśvara, as well as Bhṛgu Muni, from cursing and countercursing in that way.
