The way we deal with our emotions, experiences, and problems in meditation brings about a transformation that can certainly be described as having a therapeutic effect.
I would even call it a higher form of psychotherapy and healing.
Someone who has learned to endure and accept everything that arises in their psyche - in order to ultimately let it go - can experience profound healing.
In addition, there is the resource of God's grace and love, which has the power to heal everything.
