Jagannath Mishra was born in the village of South Dhaka in Sylhet (Sylhet). His grandfather, Madhu Mishra, had four sons: Upendra, Rangada, Kirtida, and Kirtivasa. His father and mother, Upendra Mishra and Kalavati, had seven sons: Kamsari, Paramananda, Padmanabha, Sarveshvara, Jagannath Mishra, Janardana and Trailokyanath. (Prema-vilasa, 24). According to the Gaura-ganoddesha-dipika, Upendra was Krishna's grandfather, the cowherd Parjanya, while Jagannath was Nanda Maharaj in Krishna's Vraja pastimes (Gaura-ganoddesha-dipika 37). Nanda or Jagannath were, in Krishna's various appearances, Kashyapa, Dasharath, Sutapa and Vasudeva. The king of Vraja has become Chaitanya's father, Jagannath; the queen of Vraja is his mother Sachi. The son of Nanda is Chaitanya Gosai, and Baladeva is his brother Nityananda.
(Chaitanya-caritamrita 1.17.294-295).
In the Chaitanya-caritamrita, it is also stated that Jagannath Mishra was also known by his title Purandara, which is an epithet of Indra. His wife's name was Sachidevi. Sachi's father was Nilambara Cakravarti.
(Chaitanya-caritamrita Adi, 13.59-60)
At first, eight baby girls were born to Jagannath and Sachi, but each of them died at birth. Jagannath then performed a special ceremony to have a son, and not long afterward a boy, Vishvarupa, was born. Vishvarupa is a manifestation of Baladeva and belongs to the same ontological category that is named Sankarshan in the spiritual world. At the age of 12, Vishvarupa took sannyasa, adopting the name Shankararanya. He departed in the year 1509 in Pandharpur, in the Solapur district of Maharashtra.
Jagannath Mishra and Sachidevi are eternally liberated companions of Krishna; thus, it is clear that their heart and body are made of pure goodness or the shuddha-sattva. Another name for pure goodness is vasudeva. Krishna is named Vasudeva because he takes pleasure in the spiritual nature and makes his appearance through pure goodness or vasudeva.
