Madhvacharya, also known as Madhva, is considered the founder of Dvaita Vedanta. He lived in the 13th century and is known for his rigorous philosophical arguments and his emphasis on the dualistic nature of reality.

Dvaita Vedanta posits that there are two distinct and eternal realities: Brahman, the Supreme Being, and jiva, the individual soul. This dualistic nature of reality is the central tenet of Dvaita Vedanta.

In Dvaita Vedanta, Brahman is conceived as a personal God, known as Vishnu or Narayana. Brahman is the Supreme Being, the creator, sustainer, and destroyer of the universe.

In Dvaita Vedanta, jiva refers to the individual soul. Jiva is distinct from Brahman and is characterized by its limited knowledge, power, and existence.

In Dvaita Vedanta, Brahman and jiva are considered to be distinct and different entities. This difference is fundamental and eternal.

The ultimate goal of human life in Dvaita Vedanta is to attain moksha, which is liberation from the cycle of rebirth and union with Brahman.

In Dvaita Vedanta, the primary path to moksha is bhakti, or devotion to Vishnu. Bhakti involves loving surrender to Vishnu and following his teachings.

In Dvaita Vedanta, grace is considered essential for moksha. It is believed that Vishnu's grace is necessary to overcome the limitations of the individual soul and attain liberation.

In Dvaita Vedanta, the Vedas are considered to be the ultimate authority in matters of spiritual knowledge. They are believed to be the revealed word of Vishnu and are considered infallible.

Dvaita Vedanta is incompatible with other schools of Vedanta, such as Advaita Vedanta and Vishishtadvaita Vedanta. This is because of its fundamental disagreement with their core teachings, particularly regarding the nature of reality and the relationship between Brahman and jiva.

Tattva Prakasika is a key text in Dvaita Vedanta. It is a commentary on the Brahma Sutra by Madhvacharya, the founder of Dvaita Vedanta. The text expounds on the fundamental principles and teachings of Dvaita Vedanta.

In Dvaita Vedanta, tattvas refer to categories of existence. These categories include Brahman, jiva, prakriti (matter), time, space, and various other entities. Tattvas are believed to be real and distinct from each other.

The concept of bheda (difference) in Dvaita Vedanta emphasizes the distinction between Brahman and jiva. It asserts that Brahman and jiva are fundamentally different entities and that this difference is eternal and irreducible.

In Dvaita Vedanta, maya is the power of Brahman that causes the world to appear. It is not considered to be ultimately real, but it is responsible for the creation and manifestation of the universe.

Dvaita Vedanta explains the problem of evil by attributing it to the actions of jivas. It holds that evil is a result of the misuse of free will by individual souls and is not inherent in the nature of reality.
