In the modern Hinduism, the Vedic gods like Indra(king of gods and also the sky god who control rain, thunder and lightning), Varuna(god of oceans), Vayu(wind god, who create storms and hurricanes), Agni(god of fire), Yama(god of death), Kama(god of love and lust), Rathi(wife of Kama, goddess of sexual union) etc. are no longer worshiped commonly. There may be one or two temples here and there, but not important. The commonly worshiped deities are the members of the trinity, their consorts, children and incarnations. Interestingly Brahma is not commonly worshiped. Shiva and Vishnu, the supreme Gods for the two sects of Hinduism, Shaivites and Vaishnavites, have the largest and most important temples. Saraswati, the consort of Brahma and the goddess of letters, wisdom and learning, Lakshmi, the consort of Vishnu and the goddess of prosperity and riches, and Parvati, the consort of Shiva and the goddess of power, arms and warfare, are worshiped in many places. Ganapati, the elder son of Shiva and the remover of all obstacles and Subrahmanya, the younger son of Shiva and the commander of the army of gods are also worshiped in a number of places. Then Lord Rama and Lord Krishna, and other avatars of Vishnu are widely worshiped. Then there are local deities confined to certain places. The Shaivites and the Vaishnavites were once very hostile sects who fought each other like two separate religions and also against the Buddhism and the Jainism. I think that the modern Hinduism came about as a result of the truce between the warring sects, both sects accepting their Supreme Gods as members of a supreme trinity, with Brahma as a third neutral member. Brahma is not as powerful as the other two members and he acts more like a mediator and the one who conveys the petitions and prayers of the minor gods like Indra to Vishnu and Shiva. The Vaishnavites also consider Lord Buddha as the nineth avatar (incarnation) of Vishnu after Lord Krishna.
