Brahma's fifth head!

According to Shiv Purana after Brahma created his daughter, she went around him as a mark of respect. Brahma created a woman named Shatarupa to help him with his job of creation. According to the myth, Shatarupa was so beautiful that Brahma became completely infatuated with her and stared at her wherever she went. Shatarupa was embarrassed bu this attention and tried to escape his gaze, but in every direction that she moved, Brahma sprouted a new head until he had developed four. The frustrated Shatarupa became desperate and began to jump to try to escape his gaze. This prompted Brahma to sprout yet another head on top of the others to keep her in sight.

When she flew skywards, he popped a fifth head on top of the other four. This display of unbridled passion disgusted the daughter. It is said that Shiva admonished Brahma for his "unholy" behavior towards Shatarupa and chopped off the fifth head as punishment. Brahma had given the into the carvings of the flesh and abandoned the work of the soul and for this Shiva's curse was that people should not worship Brahma.

The story also goes on to say that Brahma has been continually reciting the four vedas ever since as a form of repentance, one from each of his four heads. While Brahma is often credited as the creator of the universe and various beings in it, several puranas describe him being born from the lotus emerging from the navel of god Vishnu.  Other puranas suggest that he is born from Shiva or his aspects, or he is a supreme god in diverse versions of Hindu mythology. Brahma does not enjoy popular worship in present-age Hinduism and has lesser importance than the other members of the Trimurti, Vishnu and Shiva. Brahma is the hindu creator god. He is also known as the Grandfather and as a later equivalent of Prajapati, the primeval first god. Brahma, due to his elevated status, is less involved in picturesque myths where gods take on human form and character, but it rather generally abstract or metaphysical ideal of a great god.
