Dvaita Vedanta is considered a monotheistic philosophy, as it believes in the existence of one supreme deity, known as Brahman. According to Dvaita Vedanta, Brahman is the ultimate reality and the source of all existence. However, this does not mean that Dvaita Vedanta denies the existence of other deities or beings, but rather that they are all considered to be manifestations or aspects of Brahman.

In Dvaita Vedanta, the relationship between Brahman and the individual self, or Atman, is seen as one of distinction rather than unity. This is in contrast to other schools of Vedanta, such as Advaita Vedanta, which emphasize the concept of non-dualism, where Brahman and Atman are seen as one and the same.

The dualistic nature of Dvaita Vedanta is reflected in its belief in the existence of multiple individual souls, each with their own distinct identity and relationship with Brahman. These souls are considered to be eternal and separate from Brahman, but ultimately dependent on Brahman for their existence.

Furthermore, Dvaita Vedanta also recognizes the existence of other deities or forms of God, known as devatas, who are seen as distinct beings with their own powers and responsibilities. However, these devatas are also considered to be subservient to Brahman and ultimately derive their power and existence from Him.

In summary, Dvaita Vedanta can be considered a monotheistic philosophy due to its belief in one supreme deity, Brahman. However, it also acknowledges the existence of multiple individual souls and other deities, but sees them all as subordinate to Brahman. This dualistic perspective sets Dvaita Vedanta apart from other schools of Vedanta and highlights its emphasis on the distinction between Brahman and the individual self.
