Reality of Hindus

Brahma is the creator of the universe, Saraswati, who became the wife of her own father, was the daughter of Brahma. There are two stories about her genesis in the
“Saraswati Purana”. One is that Brahma created his beautiful daughter Saraswati direct from his “vital strength” or seminal fluid. The other is that Brahma used to collect his semen in a pot whenever he masturbated fixing his carnal eyes on the celestial beauty Urvasi. Brahma’s semen in the pot gave birth to Saraswati. Thus,Saraswati had no mother.
This daughter or grand-daughter of Brahma is the Hindu goddess of learning. When Brahma saw the beauty of Saraswati he became amorous. To escape from her father’s passionate approach Saraswati ran to the lands in all four directions, but she could not escape from her father. She succumbed to Brahma’s wish. Brahma and his daughter Saraswati lived as husband and wife indulging in incest for 100 years. They had a son Swayambhumaru. Swayambhumaru made love with his sister Satarpa. Through the incest of Brahma’s son and daughter Brahma got two grandsons and two grand-daughters.

More of Lord Brahma’s (Prajapati’s) incest:

“Prajapati desired his daughter and made love to her. This was a sin in the eyes of the gods, who said to the god who rules over beasts [Pasupati, Rudra], ‘He commits a sin, acting in this way towards his own daughter, our sister. Pierce him.’ Rudra took aim and pierced him. Half his seed fell to the ground. The gods cured Prajapati and cut out Rudra’s dart, for Prajapati is the sacrifice. To utilize [the seed], the gods said, ‘Take care that this may not be lost, but that it may be less than the oblation.’ They gave it to Bhaga to eat, but it burnt his eyes and he became blind. Then they gave it to Pusan to eat, but it knocked out his teeth. At last they gave it to Savitr [the sun] and it did not injure him, for he appeased it.” — Satapatha Brahmana 1:7:4:1-7.
