Early Vedic Religion
The prayers to propitiate gods for physical protection and for material gains were the main concerns of the Rigvedic people. The Rigvedic gods were generally personifications of different aspects of natural forces such as rains, storm, sun, etc.
The attributes of these gods also reflect the tribal and patriarchal nature of the society as we do not find many goddesses mentioned in the text. Indra, Agni, Varuna, Mitra, Dyaus, Pushana, Yama, Soma, etc. are all male gods. In comparison, we have only a few goddesses such as Ushas, Sarasvati, Prithvi, etc which occupy secondary positions in the pantheon.
The functions of different gods reflect their needs in the society. Thus, since the Rigvedic people were engaged in wars with each other they worshipped Indra as a god. He is the most frequently mentioned god in the Rigveda. He carried the thunder-bolt and was also respected as a weather god who brought rains.
Maruts the god of storm aided Indra in the wars in the way tribesmen aided their leader in the tribal wars. Agni, the fire god was the god of the home and was considered an intermediary between gods and men. Soma was associated with plants and herbs. Soma was also a plant from which an intoxicating juice was extracted. This juice was drunk at sacrifices.
Varuna, another important deity, was the keeper of the cosmic order known as rita. This rita was an important aspect of tribal setup. Pushan was the god of the roads, herdsmen and cattle. In the life of the pastoral nomads, this god must have been very important.
Other gods were similarly associated with other aspects of nature and life. All these gods were invoked and propitiated at yajnas or sacrifices. These sacrifices were organized by the chiefs of the tribes and performed by priests. Thus, Gods invoked in the sacrifices supposedly rewarded the sacrificers with success in wars, progeny, increase in cattle and long life. It also brought large number of gifts in the form of dana and dakshina to the priests.
During the entire Vedic phase, people did not construct temples nor did they worship any statue. These features of Indian religion developed much later.
