Another Legend tells, Brahma created his beautiful daughter Saraswathi direct from his vital strength. Thus, Saraswati had no mother. Saraswati is the daughter of Lord Brahma. 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 finally succumbed to Brahma's wish. Finally Brahma and Saraswati married each other.
