The medieval era Oriya scholars such as Ananta, Achyutananda and Chaitanya described the theology of Jagannath as the personification of the Shunya, or the void, but not entirely in the form of Shunyata of Buddhism. They state Jagannath as Shunya Brahma, or alternatively as Nirguna Purusha (or abstract personified cosmos). Vishnu avatars are descend from this Shunya Brahma into human form to keep dharma.
