Bhairava sometimes known as Kala Bhairava, is a Hindu deity, a fierce manifestation of Shiva associated with annihilation. He originated in Hindu mythology and is sacred to Hindus, Buddhists and Jains alike. He is worshipped in Nepal, Rajasthan, Karnataka, Tamil Nadu and Uttarakhand. Kathmandu is an unexpected and extravagant mixture of peoples and religions, child-goddesses, bare-foot porters padding in back alleys, and sacred cows. The Kathmandu most people come to see is the Old City, a tangled network of narrow alleys, stores and temples located around central Durbar Square.
