Characteristics of Vedic-era deities
In Vedic literature, Devas and Devis represent the forces of nature and some represent moral values (such as the Adityas, Varuna, and Mitra), each symbolizing the epitome of specialized knowledge, creative energy, exalted and magical powers (Siddhis).[55][56]
Vedic era deities evolved. Rudra (left) is represented in Vedic literature, is shown as Shiva-Rudra 2nd-century sculpture (middle), and as Shiva (meaning kind) in 13th-century artwork (right). The iconography evolved, retaining some symbolic elements such as trident, axe, or antelope.[57][58]
The most referred to Devas in the Rigveda are Indra, Agni (fire) and Soma, with "fire deity" called the friend of all humanity. Indra and Soma are two celebrated in a yajna fire ritual that marks major Hindu ceremonies. Savitr, Vishnu, Rudra (later given the exclusive epithet of Shiva), and Prajapati (later Brahma) are gods and hence Devas.[35]
The Vedas describes a number of significant Devis such as Ushas (dawn), Prithvi (earth), Aditi (cosmic moral order), Saraswati (river, knowledge), Vāc (sound), Nirṛti (destruction), Ratri (night), Aranyani (forest), and bounty goddesses such as Dinsana, Raka, Puramdhi, Parendi, Bharati, Mahi,among others, mentioned in the Rigveda.
Sri, also called Lakshmi, appears in late Vedic texts dated to be pre-Buddhist, but verses dedicated to her do not suggest that her characteristics were fully developed in the Vedic era.
All gods and goddesses are distinguished in the Vedic times, but in the post-Vedic texts (c. 500 BCE to 200 CE), and particularly in the early medieval era literature, they are ultimately seen as aspects or manifestations of one Brahman, the Supreme power.
Ananda Coomaraswamy states that Devas and Asuras in the Vedic lore are similar to Angels-Theoi-Gods and Titans of Greek mythology, both are powerful but have different orientations and inclinations, the Devas representing the powers of Light and the Asuras representing the powers of Darkness in Hindu mythology.
According to Coomaraswamy's interpretation of Devas and Asuras, both these natures exist in each human being, the tyrant and the angel is within each being, the best and the worst within each person struggles before choices and one's nature, and the Hindu formulation of Devas and Asuras is an eternal dance between these within each person.
The Devas and Asuras, Angels and Titans, powers of Light and powers of Darkness in Rigveda, although distinct and opposite in operation, are in essence consubstantial, their distinction being a matter not of essence but of orientation, revolution, or transformation. In this case, the Titan is potentially an Angel, the Angel still by nature a Titan; the Darkness in actu is Light, the Light in potentia Darkness; whence the designations Asura and Deva may be applied to one and the same Person according to the mode of operation, as in Rigveda 1.163.3, "Trita art thou (Agni) by interior operation".
