Lord Śiva, the spiritual master of the entire world, is free from enmity, is a peaceful personality, and is always satisfied in himself. He is the greatest among the demigods. How is it possible that Dakṣa could be inimical towards such an auspicious personality? Lord Śiva is described here as carācara-guru, the spiritual master of all animate and inanimate objects. He is sometimes known as Bhūtanātha, which means "the worshipable deity of the dull-headed." Bhūta is also sometimes taken to indicate the ghosts. Lord Śiva takes charge of reforming persons who are ghosts and demons, not to speak of others, who are godly; therefore he is the spiritual master of everyone, both the dull and demoniac and the highly learned Vaiṣṇavas. It is also stated, vaiṣṇavānāṁ yathā śambhuḥ: Śambhu, Lord Śiva, is the greatest of all Vaiṣṇavas. On one hand he is the worshipable object of the dull demons, and on the other he is the best of all Vaiṣṇavas, or devotees, and he has a sampradāya called the Rudra-sampradāya. Even if he is an enemy or is sometimes angry, such a personality cannot be the object of envy, so Vidura, in astonishment, asked why he was taken as such, especially by Dakṣa. Dakṣa is also not an ordinary person. He is a Prajāpati, in charge of fathering population, and all his daughters are highly elevated, especially Sati. The word satī means "the most chaste." Whenever there is consideration of chastity, Sati, this wife of Lord Śiva and daughter of Dakṣa, is considered first. Vidura, therefore, was astonished. "Dakṣa is such a great man," he thought, "and is the father of Sati. And Lord Śiva is the spiritual master of everyone. How then could there possibly be so much enmity between them that Sati, the most chaste goddess, could give up her body because of their quarrel?"

When that gigantic demon asked with folded hands, "What shall I do, my lord?" Lord Śiva, who is known as Bhūtanātha, directly ordered, "Because you are born from my body, you are the chief of all my associates. Therefore, kill Dakṣa and his soldiers at the sacrifice." Here is the beginning of competition between brahma-tejas and śiva-tejas. By brahma-tejas, brahminical strength, Bhṛgu Muni had created the Ṛbhu demigods, who had driven away the soldiers of Lord Śivastationed in the arena. When Lord Śiva heard that his soldiers had been driven away, he created the tall black demon Vīrabhadra to retaliate. There is sometimes a competition between the mode of goodness and the mode of ignorance. That is the way of material existence. Even when one is situated in the mode of goodness, there is every possibility that his position will be mixed with or attacked by the mode of passion or ignorance. That is the law of material nature. Although pure goodness, or śuddha-sattva, is the basic principle in the spiritual world, pure manifestation of goodness is not possible in this material world. Thus, the struggle for existence between different material qualities is always present. This quarrel between Lord Śivaand Bhṛgu Muni, centering around Prajāpati Dakṣa, is the practical example of such competition between the different qualitative modes of material nature.
