Lord Vishnu, is generally symbolized by a human body with four arms. In His hands He carries a conch (shankha), a mace (gada), and discus (chakra). He wears a crown, two earrings, a garland (mala) of flowers, and a gem around the neck. He has a blue body and wears yellow clothes. The Lord is shown standing on a thousand-headed snake (named Shesha Naga), and the snake stands with its hoods open over the head of the Lord.
The four arms indicate Lord's omnipresence and omnipotence. The two front arms signify the lord's activity in the physical world and the two back arms signify His activity in the spiritual world. The right side of the body represents the creative activities of the mind and the intellect. The left side symbolizes the activities of the heart; that is, love, kindness, and compassion.
A conch in the upper left hand indicates that the Lord communicates with His devotees with love and understanding. When blowing His conch, He reminds his devotes to live in this world with kindness and compassion towards all living beings.
A chakra in His upper right hand conveys the idea that the Lord uses this weapon to protect His devotees from evil.
The mace denotes energy and a mace in the Lord's left lower hand signifies that He sustains the manifest world by the energy that He holds in Himself. His front right hand is depicted bestowing grace on His devotees.
A flower garland around the Lord's neck is a symbol of the devotee's adoration for the Lord. A gem decorating His neck signifies that the Lord fulfills all genuine desires of His devotees and provides for their needs. The crown is a symbol of the Lord's supreme power and authority. The two earrings signify the dual nature of creation, such as knowledge and ignorance, happiness and unhappiness, and pleasure and pain.
