Vedism was a polytheistic sacrificial religion involving the worship of numerous male divinities and goddesses, most of whom were connected to the natural phenomena. The priests who officiated at the worship were drawn from Brahman social class. Vedic ceremonies, for which the hymns of the Rig-Veda were composed for rituals sacrifices.
The ancient Vedic worshippers offered sacrifices to those Gods in the hope that they in return would grant abundant numbers of cattle, good fortune, good health, long life and made progeny, among other material benefits.
The rites of Vedic sacrifice were relatively simple in the early period, when the Rig-Veda was composed. They required neither temple nor images. The ceremonies took place in an open space. The installation of the Fire (Agni ) was necessary, preliminary to all the large public rituals.
The legacy of Vedic worship is apparent in several aspects of modern Hinduism. The basic stratification of Vedic society into four Varna’s. The Brahman ( Priests ), The Kshatriyas ( Warriors or Rulers ) The Vaishyas ( Traders ) and Shudras ( Servants ) by and large persisted in later Hinduism.
But the question was who is the supreme God. Different forms (Avatars ) of the supreme God are worshipped, depending on the Hindu Tradition. The other gods, who are helpers of the supreme God, are also worshipped. Brahma, Vishnu and Shiva are the major gods and Laxmi, Parvati and Saraswati are the major Goddesses in Hinduism.
According to Hinduism the supreme God is Shiva. For practical purposes a Hindu can choose among Shiva, Vishnu, Krishna and Shakti in their supreme forms. Shiva is the most powerful, Vishnu is the most versatile, Krishna is simple and powerful and Shakti is always available. Thus different sections of Hindu society use different supreme gods. The role of Shiva is to reduce satisfaction and facilitate action. Shiva makes it automatic, Vishnu makes it Semi- automatic and Brahma makes an activity manual. Shakti is illusory force, it just gives us an illusion of courage and satisfaction. Shakti is considered as a manifestation of Parvati, who is the consort of Shiva. Parvati is the feminine part of Shiva. Durga and Kali are goddesses considered as incarnations of Parvati, and in the same way Hanuman is the son of Shiva considered god.
Different Hindu practices allow for various representations of God, but each representation (Deities ) is in itself a depiction of God. Hindu believe that one supreme god cannot be fully understood, so earthly representation are symbolic of supreme God and people decide whichever representation of god, they prefer at any given time. A devoted person can relate to god as a majestic king, as a parent figure, as a friend, as a child, as a beautiful woman or even as a ferocious goddess. Thus, one person might be drawn towards Shiva, another towards Krishna, and another towards Kali. Many Hindu believe that all the different deities are aspects of a single transcendent power.
