Our emphasis here is on Shikantaza .
.. which may be said to be "being one" with what ails one, although not necessarily a cure for what ails one. HOWEVER, that "being one" with life ... can relieve much suffering in life. It is a strange thing ... we do not
sit Shikantaza to be "better" or to make life "other than as it is" ...
... Yet, in the very stillness of letting life be "as is it
" and embracing all of life ... and in dropping the hard borders and divisions between our "self" and the world ... this practice does thereby leave almost all people better ... and often does work an effective cure (or is one helpful part
of the cure) ... from depression, stress, addiction, compulsive disorders, eating disorders, anger issues, self loathing ... you name it.
We do emphasize mindfulness of our thoughts and emotions ... but not as a form of meditation. However, our Zazen is the radical non-doing of Shikantaza, and the "mind theatre" and tricks and games of the human mind is something that naturally we also become better able to recognize and avoid from sitting.
... I suspect that Shikantaza ... in its quietness, in the total stillness and acceptance ... would be something helpful with what you describe ...
Zazen is -NOT- a cure for many things ... it will not fix a bad tooth (just allow you to be present with the toothache ... you had better see a dentist, not a Zen teacher
), cure cancer (although it may have some healthful effects and make one more attune to the process of chemotherapy and/or dying
), etc. Zen practice will not cure your acne on your face, or fix your flat tire. All it will do is let one "be at one, and whole" ... TRULY ONE ... with one's pimples and punctured wheel, accepting and embracing of each, WHOLLY WHOLE with/as each one. There are many psychological problems or psycho/medical problems such as alcoholism that may require other therapies, although Zen can be part of a 12-Step program or such (a few Zen teachers in America with a drinking problem had to seek outside help
). My feeling is that some things are probably best handled by medical, psychological or psychiatric treatment, not Zen teachers.
My feeling is that receiving outside treatment, medication AND "just sitting" can all work together.
