Lord Vishnu, one of the Trinity Supreme, is the Lord of Preserver. He is of blue in color and having four arms with Conch, Discuss, Lotus and Mace on it. The name Vishnu comes from the root VISH, which means, "to spread in all directions, to pervade". He is the inner center, the core, the nucleus, and the cohesive point through which everything exists. He swells in everything, owns everything and overcomes any thing. The two most common representations of Vishnu show him either sleeping over the waves of the ocean on the coils of the serpent-deity, named Shesh Nag, or standing on waves with four hands each hand holding one of his four chief attributes.  The worshippers of Lord Vishnu are called as "Vaishnavas". To protect, restore and preserve the universe from the evil forces Lord has incarnated Himself in the form of  "Avatar". He is blue-skinned and in all pictures and images and he is seen in rich ornaments and regal garments. His wife is Lakshmi or Sri, the goddess of wealth and fortune. His place of abode is VAIKUNTHA (heaven) and his vehicle is Garuda, a giant -sized eagle, which often is shown as a winged human-shaped figure having a beak-like nose. Vishnu is the infinite ocean from which the world emerges. Hence his symbol is water (Nara) and he himself is called 'NARAYANA ' - the one who dwells upon the waters. He is pictured with the many-headed snake, as mentioned above, and this denotes ANANT NAG (the timeless or ageless snake). From his navel grows the lotus out of which appears Brahma, the god who created the universe.
