1.2.40  Shiva Married Sati

Lord Shiva was anxiously waiting for his arrival. When Lord Brahma arrived he curiously asked about Daksha's response. When lord Brahma told him about Daksha's approval of the marriage. Shiva was very pleased at this.

Lord Shiva proceeded towards Daksha's abode on the auspicious moment of Phalgun, Krishnapaksha and on the thirteenth day of Phalguni Nakshatra. Sitting on the back of Nandi and accompanied by all the deities including lord Brahma, Vishnuji he reached Daksha's residence.

The marriage-procession was received by Daksha with great respect. Shiva narrated Sati in an auspicious lagna. Being pleased, all the deities eulogised Shiva and danced in joy.

1.2.41  Lord Brahma Faces the Wrath of Shiva

Daksha presented invaluable things to his daughter- Sati as dowry. Similarly the brahmins were presented with large quantities of wealth.

Lord Brahma was enchanted by the divine beauty of Sati. With a desire to see her face, he put logs of wood which were wet, into the yagni kunda and poured ghee on them. As a result the atmosphere was filled up with smoke.

Now Brahma removed the piece of cloth which covered her face. He became infatuated by her beauty. When lord Shiva discovered about his evil intentions he ran towards him menacingly. Lord Shiva wanted to kill him, but the deities prayed to spare his life. Lord Vishnu eulogised and worshipped him and only then his anger was subdued. Thus lord Brahma was forgiver by Shiva.

1.2.42  Deformed Face of Brahma

Though lord Shiva had forgiven Brahmaji, yet he instructed him to apologize by bowing down his head. Brahma did as he was instructed Lord Shiva then established on his head. Brahmaji became ashamed and asked as to how could he atone for his sins. Lord Shiva instructed Brahmaji that by worshipping him he could appropriately atone for his sins. He than instructed Brahma to go to the earth where he would be worshipped as 'Rudra Shir'. Shiv said-

"Your worship would help the brahmin in accomplishing every kinds of work. Taking lessons from you people would not dare to have extramarital affairs.
