Vedic deities are those deities who are mentioned in the Holy Vedas and Puranas, and they receives their share of oblation from the fire sacrifices, and they include Indra, Surya, Agni, Ushas, Vayu, Varuna, Mitra, Aditi, Yama, Soma, Saraswati, Prithvi, and Rudra.
In the Rigveda, the names and the importance of the Vedic deities are mentioned. The Heaven god Indra, is mentioned as the destroyer of Demon Vritrasura, and as the chief of the Devas, and Lord Chandra, is one of the Navagrahas and gives coolness to us through his supreme powers, and similarly other Vedic deities are also discharging their duties in a fantastic manner, and gives all kinds of prosperity to us.
Lord Rudra, Yama, Surya, Varuna, Vayu and Agni are the most important Vedic gods, and they give comforts and luxuries, and help us to lead a stress free life. Lord Brahma and his consort Mata Saraswati are considered to be the deities of Vedas, and they are also eligible to receive the oblation from the fire sacrifices, and they must be worshipped for getting good knowledge in all the subjects.
According to ancient Puranas, some Vedic gods are believed to have committed some mistakes during the Vedic period due to their bad fate. But after that, they realized their mistakes and become very pious and holy. Sometimes fate is written badly even to the demigods, and they also cannot escape from the fate. But instead of thinking about the past history of the Vedic gods, it is suggested to worship them wholeheartedly. Since, we are all humans, and we didn’t have super natural powers, we must have to compulsorily bow our head before all the Vedic deities, and must show our respect and faith on them.
Analysing about their nature, or about their history, would not fetch anything for us. Instead of that, we must praise the Vedic gods and goddesses by chanting their holy mantras, attending the Yagnas conducted in the temples, and must seek their mercy. Since the Vedic deities are formed before millions and millions of years ago, we must praise about their greatness, sing songs on them, study the history of Vedic deities from the Vedas and the Puranas, and must realize their importance throughout our life.
