According to Dvaita Vedanta, the concept of God is explained through the principles of dualism, where Atman (individual self) and Brahman (universal self) are considered distinct entities. This philosophy believes that God is the supreme being who is separate from the individual self and is the creator and sustainer of the universe.

In Dvaita Vedanta, God is known as Vishnu or Narayana, who is believed to be the ultimate reality and the source of all existence. He is described as the all-knowing, all-powerful, and all-pervading being who is the cause of all creation and the ultimate goal of human life.

The relationship between God and the individual self is compared to that of a master and servant, where God is the master and the individual self is the servant. This relationship is based on the principle of Bhakti (devotion), where the individual self surrenders to God with love and devotion.

Dvaita Vedanta also explains the concept of God through the notion of Saguna Brahman, which means Brahman with attributes. This means that God is not just an abstract concept but has a form and attributes that can be perceived and worshipped by the devotees. This form of God is believed to be a manifestation of the ultimate reality and is accessible to the individual self through devotion and prayer.

Furthermore, Dvaita Vedanta also emphasizes the importance of the relationship between God and the individual self. It is believed that through this relationship, the individual self can attain moksha (liberation) and merge with God. This is achieved through the practice of Bhakti yoga, which involves constant remembrance and devotion to God.

In conclusion, Dvaita Vedanta explains the concept of God as the supreme being who is separate from the individual self and is the creator and sustainer of the universe. The relationship between God and the individual self is based on devotion and surrender, and through this relationship, one can attain liberation and merge with God.
