Brahma's Creation, Saraswati
Brahma is the creator and also created Saraswati. Saraswati is half-man and half-woman. Saraswati is also the wife of Brahma. Saraswati is the goddess of learning, knowledge and speech. She is the goddess of speech because it's a way to express her knowledge of things. Saraswati is the protector of art and is the creator of writing. She is thought of a river by many people, but she is celebrated as a river and a supernatural person.
This is because Saraswati is a sacred river. Now, it's dried up. People believe that it was dried up because it was a curse by the sage Uthya. Her job as a river to purify the water that is given for people to drink. This also proves why she is always standing or sitting on a lily while playing a lute. Dr. Muir explains Saraswati as the protector of rituals and ceremonies which gives away her character. That proves a lot why Brahma would create Saraswati. Brahma also has a reason for falling in love with his own creation.
