Dvaita Vedanta is a philosophical school within Hinduism that emphasizes the concept of dualism, or the belief that there are two distinct realities - the individual self (Atman) and the universal consciousness (Brahman). This school of thought was founded by the 13th century Indian philosopher Madhvacharya and is also known as Madhva Vedanta.

According to Dvaita Vedanta, the individual self (Atman) is separate from the ultimate reality (Brahman). While Brahman is the supreme, eternal, and unchanging consciousness, Atman is the individual soul that experiences the world through the physical body. This duality is seen as the fundamental truth of existence.

One of the key principles of Dvaita Vedanta is the concept of Bhakti, or devotion. It teaches that through devotion and surrender to God, one can attain liberation from the cycle of birth and death and merge with Brahman. This devotion is expressed through rituals, prayers, and worship of a personal deity, who is seen as a manifestation of Brahman.

Dvaita Vedanta also emphasizes the importance of karma, or the law of cause and effect. It teaches that every action has consequences and one must bear the fruits of their actions, whether good or bad. However, through devotion to God, one can overcome the effects of negative karma and attain liberation.

Another key aspect of Dvaita Vedanta is the concept of maya, or illusion. It teaches that the material world is a manifestation of maya and is not the ultimate reality. The true reality lies beyond the material world, in the form of Brahman.

In Dvaita Vedanta, the relationship between Atman and Brahman is seen as that of a servant and master. Atman is seen as the servant of Brahman and is dependent on Brahman for its existence. This relationship is compared to that of a wave and the ocean - the wave is separate from the ocean, but it is made up of the same substance.

In conclusion, Dvaita Vedanta is a school of thought that emphasizes the duality of the individual self and the ultimate reality, and the importance of devotion, karma, and the concept of maya. It offers a path to liberation through devotion to a personal deity and understanding the true nature of reality.
