In hindu mythology Brahma is known as the creator of the universe, along with Vishnu who is the protector of earth and Shiva who brings transformation and destruction to the earth. He is the part of the sacred trimurti. But if you look here you will find temples of Vishnu and Shiva and people are also worshipping them but no one is worshipping Brahma. The reason comes from an old story about pride, honesty, and a powerful curse.
