Born from the lotus in Vishnu's navel, Brahma is often depicted as a four-faced god sitting on a lotus flower. According to some Hindu writings, Brahma laid the egg that hatched the universe. He is said to have written the Rig-Veda on golden leaves. A day in the life of Brahma lasts about 4,320,000,000 years, after each of these days everything that is living is destroyed so it may be reborn in the Hindu cycle of life and death.
