The Healer's Tale of the Ninth Heaven

Above the first heaven dwells an immortal; above the ninth heaven dwells a high immortal. High immortals were once mortals who cultivated their way to immortality, then crossed the mortal realm to save mortals. The mortal world is rife with suffering and sickness. When illness comes, resentment and anger take root in the heart. Resentment and anger breed inner demons, and the way of demons emerges clearly as the Heavenly Physician.
