A Basic Toratherapeutic Thought - Tracht Gut Vet Zein Gut
The Lubavitcher Rebbe, Rabbi M.M. Schneerson, speaks about healing, health and mental health in many of his talks and writings (especially in the Igros Kodesh - Holy Letters). There is a book that came out fairly recently (last year) that is a collection of letters that the Rebbe wrote to people about health and healing. It's awesome... Its title: Healthy in Body, Mind and Spirit. The second volume (which will hopefully come out this year) is about mental health and Chassidic philosophy. (The whole book is available online at Sichos in English - www.sichosinenglish.org.) The Rebbe often quoted a saying of the Rebbeim, "Tracht gut vet zein gut...Think positively, and you will see positive results."
The concepts of positive thinking, affirmations, post hypnotic suggestions, etc., are often used in therapy practice, and have significant therapeutic merits. I guess someday science will catch up with the Torah...
Here is an excerpt from volume one which is originally from Igros Kodesh (The Holy Letters) Volume X, p. 358:
"... I believe that in the past I have already told you about the statement in the sacred Zohar (II, p. 184b) that when man below is of a “radiant countenance” and filled with joy and gladness, he then draws down upon himself the same qualities from Above.
This provides us with an even better understanding of the aphorism of our holy Rebbeim: “Think positively, and you will see positive results.”
