Hinduism believes that there is only one supreme Absolute called "Brahman".
However, says Hindusim.about.com, it does not advocate the worship of any one particular deity.
The gods and goddesses of Hinduism amount to thousands or even millions, all representing the many aspects of Brahman. Therefore, this faith is characterized by the multiplicity of deities.
The most fundamental of Hindu deities is the Trinity of Brahma, Vishnu and Shiva - creator, preserver and destroyer respectively. Hindus also worship spirits, trees, animals and even planets.
