In the basic Hindu Trinity of Brahma, Vishnu and Shiva, the Hindu god Vishnu is the preserver and protector of creation. Vishnu is the embodiment of mercy and goodness, the self-existent, all-pervading power that preserves the universe and maintains the cosmic order Dharma. Vishnu is often represented resting on the coiled serpent Shesha, with Vishnu's consort Lakshmi massaging his feet. Vishnu never sleeps and is the deity of Shanti, the peaceful mood. Vishnu does not however tolerate ego. Most often, the Hindu god Vishnu is shown with four attributes or weapons. In one hand Vishnu holds the conch or Sankha. The second hand of Vishnu holds the disc or Vaijra. The third hand of Vishnu holds the club and in the fourth hand Vishnu holds the lotus or Padma. Vishnu also has a bow called Sarnga and a sword called Nandaka. Most of the time, good and evil forces are evenly matched in the world. But at times, the balance is destroyed and evil demons get the upper hand. Often in response to a request by the other gods, Vishnu then incarnates in a human form to set the balance right again. 9 Vishnu incarnations are generally recognized as Vishnu avatars, even though some sources also see other important figures of the indian epics as incarnations of Vishnu.
