I think meditation can be therapeutic but should not really be seen as the same as therapy. I respect Mark Epstein's work but I think he should be a bit more conservative in his claims that medication can heal trauma. At first this seemed true, then it was found (in a program in Boston with veterans) that meditation often agitated symptoms of severe PTSD. I am a certified meditation instructor. I often advise students to seek out therapy if they have personal issues with extremely intense emotions that meditation highlights. This often happens with younger people who are first away at college and who are experiencing a lot of new stress. Sitting meditation practice might also not be good for someone with severe dissociative disorder symptoms.
