Dvaita Vedanta is a school of Hindu philosophy that was founded by Madhvacharya in the 13th century. It is also known as Tattvavada or Dualistic philosophy. Dvaita means duality or dualism, and Vedanta refers to the end or culmination of the Vedas, the sacred texts of Hinduism.

According to Madhvacharya, the ultimate reality is Brahman, the supreme being, who is the creator, sustainer, and destroyer of the universe. However, unlike other schools of Vedanta, Madhvacharya believed that Brahman is not the only reality. He argued that there are two other eternal and independent realities - Jiva (individual soul) and Jagat (universe).

Dvaita Vedanta states that Jiva and Jagat are distinct from Brahman and are not mere illusions or manifestations of Brahman. Jiva is a conscious being, while Jagat is the material world. Both Jiva and Jagat are dependent on Brahman for their existence, but they are not the same as Brahman.

Madhvacharya also believed in the concept of Srishti-Drishti-Vada, which means creation-perception theory. According to this theory, Brahman created the universe and then revealed it to the individual souls for their perception. This is in contrast to the Advaita Vedanta philosophy, which states that the universe is an illusion and only Brahman is real.

Dvaita Vedanta also emphasizes the concept of Bhakti or devotion to God. Madhvacharya believed that through devotion and surrender to God, one can attain liberation from the cycle of birth and death. He also emphasized the importance of following the path of Dharma or righteousness in order to lead a virtuous life and attain moksha or liberation.

One of the key principles of Dvaita Vedanta is the concept of Tattvavada, which means understanding the true nature of reality. According to Madhvacharya, the ultimate goal of human life is to understand the true nature of Brahman, Jiva, and Jagat, and their relationship with each other.

In conclusion, Dvaita Vedanta is a school of Hindu philosophy that emphasizes the duality of Brahman, Jiva, and Jagat. It teaches the importance of devotion to God, following the path of righteousness, and understanding the true nature of reality. The teachings of Madhvacharya continue to influence and inspire many people in their spiritual journey towards self-realization and liberation.
