Summary:

Lazarus’s study (1976) concentrated on Transcendental Meditation. It concluded that while the practice was shown to be beneficial, this was not universal and could initiate psychiatric problems such as depression, anxiety and schizophrenia and was therefore not suitable for everyone.

Abstract:

Like many procedures, Transcendental Meditation (TM) proves extremely effective when applied to properly selected cases by informed practitioners. It is not a panacea. In fact, when used indiscriminately, there are clinical indications that the procedure can precipitate serious psychiatric problems such as depression, agitation, and even schizophrenic decompensation.
