Your opinion on psychoanalysis ? on analysis ?
on the free association of ideas ? on the unconscious ?
I believe that the practice of zazen is not directly made to cure neurosis and illnesses, say, of the unconsciousness. It is a bit similar to a mixed up string. Zen helps us to get free of this string in a very high dimension, to understand that this string is not our real ego, to go beyond our karma, to see it in its totality. But some times, for some blockages, for some repetitions of wrong behaviour, a therapy, either a traditional freudian therapy, or modern therapies like the ericksonian ones, can be quite effective in getting a solution to some karma problems.
