"Thus Lord Siva, being extremely angry, pressed his lips with his teeth and immediately snatched from his head a strand of hair which blazed like electricity or fire. He stood up at once, laughing like a madman, and dashed the hair to the ground.
A fearful black demon as high as the sky and as bright as three suns combined was thereby created, his teeth very fearful and the hairs on his head like burning fire. He had thousands of arms, equipped with various weapons, and he was garlanded with the heads of men.
When that gigantic demon asked with folded hands, "What shall I do, my lord?" Lord Siva, who is known as Bhutanatha, directly ordered, "Because you are born from my body, you are the chief of all my associates. Therefore, kill Daksa and his soldiers at the sacrifice."
Purport: Here is the beginning of competition between brahma-tejas and siva-tejas. By brahma-tejas, brahminical strength, Bhrgu Muni had created the Rbhu demigods, who had driven away the soldiers of Lord Siva stationed in the arena. When Lord Siva heard that his soldiers had been driven away, he created the tall black demon Virabhadra 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 suddha-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 Siva and Bhrgu Muni, centering around Prajapati Daksa, is the practical example of such competition between the different qualitative modes of material nature.
Maitreya continued: My dear Vidura, that black person was the personified anger of the Supreme Personality of Godhead, and he was prepared to execute the orders of Lord Siva. Thus, considering himself capable of coping with any power offered against him, he circumambulated Lord Siva.
Many other soldiers of Lord Siva followed the fierce personality in a tumultuous uproar. He carried a great trident, fearful enough to kill even death, and on his legs he wore bangles which seemed to roar.
At that time, all the persons assembled in the sacrificial arena--the priests, the chief of the sacrificial performance, and the brahmanas and their wives--wondered where the darkness was coming from. Later they could understand that it was a dust storm, and all of them were full of anxiety.
Conjecturing on the origin of the storm, they said: There is no wind blowing, and no cows are passing, nor is it possible that this dust storm could be raised by plunderers, for there is still the strong King Barhi, who would punish them. Where is this dust storm blowing from? Is the dissolution of the planet now to occur?
Prasuti, the wife of Daksa, along with the other women assembled, became very anxious and said: This danger has been created by Daksa because of the death of Sati, who, even though completely innocent, quit her body as her sisters looked on.
At the time of dissolution, Lord Siva's hair is scattered, and he pierces the rulers of the different directions with his trident. He laughs and dances proudly, scattering their hands like flags, as thunder scatters the clouds all over the world.
The gigantic black man bared his fearful teeth. By the movements of his brows he scattered the luminaries all over the sky, and he covered them with his strong, piercing effulgence. Because of the misbehavior of Daksa, even Lord Brahma, Daksa's father, could not have been saved from the great exhibition of anger.
While all the people talked amongst themselves, Daksa saw dangerous omens from all sides, from the earth and from the sky.
My dear Vidura, all the followers of Lord Siva surrounded the arena of sacrifice. They were of short stature and were equipped with various kinds of weapons; their bodies appeared to be like those of sharks, blackish and yellowish. They ran all around the sacrificial arena and thus began to create disturbances.
