The Rig Vedic period is considered to be one of the earliest periods in Indian history, dating back to around 1500-1000 BCE. It is named after the collection of hymns known as the Rigveda, which is one of the oldest sacred texts of Hinduism. During this period, the people worshipped a variety of deities, each associated with different aspects of life and nature.

Let's take a look at the deities associated with the Rig Vedic period:

1. Purandara: Purandara is another name for the Vedic deity Indra. He is considered to be the king of gods and is associated with thunder, rain, and war. Indra is often depicted as a warrior riding a chariot and wielding a thunderbolt. He is praised for his strength and bravery in the Rigveda.

2. Varuna: Varuna is one of the most prominent deities in the Rigveda. He is associated with the cosmic order and is often described as the god of the sky and the waters. Varuna is believed to have the power to punish those who violate moral and ethical codes. He is also associated with justice and truth.

3. Savitri: Savitri is a deity associated with the sun and is often referred to as the solar deity. In the Rigveda, Savitri is praised for his life-giving power and his role in sustaining the world. He is considered to be the source of all energy and is often invoked for blessings and protection.

4. Usha: Usha is the Vedic goddess of dawn. She is associated with the transition from darkness to light and is often depicted as a beautiful maiden. Usha is praised for bringing light and new beginnings to the world. Her hymns in the Rigveda symbolize hope and the renewal of life.

In conclusion, all four deities mentioned - Purandara (Indra), Varuna, Savitri, and Usha - were associated with the Rig Vedic period. They played significant roles in the religious and cultural beliefs of the people during that time, as reflected in the hymns of the Rigveda.
