They must find within themselves the divine presence. Only when they find this close relationship with God can they be healed. They must work to sustain this connection with God, that it should grow. To do this they need the Torah. The first connection with God for the mentally ill is through prayer and meditation.
Prayer is with the eyes open in most cases, and meditation is with the eyes closed.
Meditation is an extension of prayer, the service of the heart. The work of the healer is to bring God closer, from the distant heavens down to the earth below in the heart of flesh. To do this is needed a correction of the soul, to unite the soul with its source which is above thought. With this connection to its source which is above thought, can be controlled and overcome the bad destructive thoughts of the mind. These thoughts can be pushed away from the conscious mind.
