Spiritual Healing
The Medzibozer Rabbi said: "The Psalmist declares: 'O Lord, my God, I cried loudly to You and You did heal me.' (Pslams 30:3) This signifies that the act of crying to God is in itself a source of healing for spiritual ailments."
The Kobriner finds this in the words: "For I am the Lord that heals you" (Exodus 15:26); "The knowledge that God is the Lord is a cure for maladies of the mind and heart."
