In this excerpt from his thesis, Dr Ramesh Manocha discusses the potential adverse effects of meditation.
From the review presented in Chapter 2 it was clearly evident that there is no convincing evidence to suggest that meditation has a specific effect. At least one other review agrees with this conclusion. In light of this, and the distinct possibility that meditation, or at least some techniques of meditation, are associated with adverse effects, a close examination of the literature is imperative for us to develop a clear understanding of the “risk benefit ratio” associated with this phenomenon.
