Job was walking on the road and met Elijah. Elijah said to him, “What ails you?” “My head and whole body hurt!” said Job. “Go and immerse in the River of Fire,” said Elijah, “and you will be healed!” Job went to the River of Fire, immersed, and was healed. Just as Job was healed, so may all the sick of Israel be healed! (Siach Sarfei Kodesh [Breslov], vol.5, p.188, #457)
Elijah is the heavenly messenger to save us from our troubles. His disciple, Elisha, told the sick Aramean general, Naaman, to immerse in the Jordan River; and he was healed. The cosmic River of Fire separates us from heaven. If we accept an immersion of divine fire, we are spared and saved from earthly pain and suffering. We attain heavenly delight despite our suffering. Even Job can be free of his afflictions.
