Ganesh Puja can remove all the obstacles to success and confer peace, prosperity and the divine protection of Lord Ganesh. It can promote harmony in families and bless the devotees with siddhi (powers) and buddhi (intelligence). Puja is the act of showing reverence to a god, a spirit, or another aspect of the divine through invocations, prayers, songs, and rituals. An essential part of puja for the Hindu devotee is making a spiritual connection with the divine.
Most often that contact is facilitated through an object: an element of nature, a sculpture, a vessel, a painting, or a print. During puja an image or other symbol of the god serves as a means of gaining access to the divine. This icon is not the deity itself; rather, it is believed to be filled with the deity's cosmic energy. It is a focal point for honoring and communicating with the god. For the devout Hindu, the icon's artistic merit is important, but is secondary to its spiritual content. The objects are created as receptacles for spiritual energy that allow the devotee to experience direct communication with his or her gods. Ganpati or Ganesha, the Lord of Ganas, the elephant faced God, represents the power of the Supreme Being that removes obstacles and ensures success in human endeavors.
Ganesha is revered as the son of the Shiva and Parvati, and is always honored first in most worship services and rituals. Ganesha is also known as Ganpati, Vigneswara, Vinayaka, Gajamukha and Ainkaran. He is worshipped for Siddhi, success in undertakings, and Buddhi, intelligence. He is worshipped before any venture is started. He is also the God of education, knowledge and wisdom, literature, and the fine arts.
