Dasaavathar of LORD VISHNU
The preserver god of the Trinity has four hands. The first holds a conch shell (sankha) indicating spread of the divine sound "Om"; one holds a discus (chakra), a reminder of the wheel of time, and to lead a good life; one holds a lotus (Padma) which is an example of glorious existence and the fourth hands holds a mace (gada) indicating the power and the punishing capacity of the Lord if discipline in life is ignored. His vehicle is the swift-flying bird Garuda which can spread the Vedic knowledge with great courage. The dark color of the Lord represents the passive and formless ether, a great quality for a pervading god. He rests on the bed of the powerful, coiled serpent, Seshanag who represents the sleeping universe. Lord Vishnu is also known as Hari, the remover. Lord Vishnu's consort is Goddess Lakshmi, the Goddess of Wealth .
Lord Vishnu's preserving, protecting powers have been manifested to the world in a variety of forms, called Avatars, in which one or more of his divine attributes were embodied in the shape of a human being or an animal or a human-animal combined form, possessing great and sometimes supernatural powers. All these Avatars of Vishnu appeared in the world either to correct some great evil or to effect some great good on earth. These avatars are ten in number, however, the Bhag wad Purana increases them to twenty two and adds further that are innumerable.Of the ten universally recognized avatars, nine have already manifested whereas the tenth is yet to appear. It is important to note that the all the Avatars are earthly form of Lord Vishnu , who himself is eternal, unchangeable and immutable.
