Jagannath Baladeva Subhadra Devi

jagannātha-svāmī nayana-patha-gāmī bhavatu me
“O Lord of the universe, please be visible unto me.”

Lord Jagannātha is the Supreme Lord Himself in the form of wood, and the river Ganges is the Supreme Lord Himself in the form of water.
(CC Madhya 15.135)

Jagat means moving. And Jagat-nātha, nātha means the proprietor—master, proprietor. So Jagannātha means the proprietor or the master of all these movements, He is Jagannātha. And Balabhadra, Balarāma, bala means strength, and rāma means enjoyment. So Balarāma means who gives you spiritual strength for enjoying eternal blissful life. He is Balarāma. And Subhadrā, su means auspicious, and bhadra means well-being. Subhadrā, Jagannātha and Balarāma combined together are present before you to reclaim you all from your miserable condition of life. That is the purport of this Ratha-yātrā Festival. Ratha-yā . . . (break) . . . if anyone sees on the car Jagannātha, Subhadrā and Baladeva, then he does not take birth again in this material world. Ratheja vamanaṁ dṛṣṭa.

Lord Jagannātha is the Supreme Personality of Godhead. He possesses all potencies. Therefore He is able to act freely and can do and undo whatever He likes.
(CC Antya 9.44)

Subhadrā: Daughter of Vasudeva and sister of Lord Śrī Kṛṣṇa. She was not only a very dear daughter of Vasudeva, but also a very dear sister to both Kṛṣṇa and Baladeva. The two brothers and sister are represented in the famous Jagannātha temple of Purī, and the temple is still visited by thousands of pilgrims daily.
(SB 1.13.3-4)
