The theology and rituals associated with the Jagannatha tradition combine Vedic, Puranic and tantric themes. He is the Vedic Purushottama, the Puranic Narayana and the tantric Bhairava. He is same as the metaphysical Brahman, the form of Lord Krishna that prevades as abstract kāla (time) in Vaishnava thought. He is abstraction which can be inferred and felt but not seen, just like time. Jagannath is chaitanya (consciousness), and his companion Subhadra represent Shakti (energy) while Balabhadra represents Jnana (knowledge). According to Salabega, the Jagannath tradition assimilates the theologies found in Vaishnavism, Shaivism, Shaktism, Buddhism, Yoga and Tantra traditions.
