Synaesthesia is considered a rare perceptual capacity, and one that is not capable of cultivation. However, meditators report the experience quite commonly, and in questionnaire surveys, respondents claimed to experience synaesthesia in 35% of meditation retreatants, in 63% of a group of regular meditators, and in 86% of advanced teachers. These rates were significantly higher than in nonmeditator controls, and displayed significant correlations with measures of amount of meditation experience. A review of ancient texts found reports suggestive of synaesthesia in (...) advanced meditators from India and China. These findings suggest that synaesthesia may be cultivated by meditation, and that laboratory studies of meditators could be rewarding. (shrink)

Despite 40 years of dialogue, debate still continues over whether psychedelics are capable of inducing genuine mystical experiences. This paper first reviews the arguments against this possibility and shows that all of them contain shortcomings. One reason the debate still continues is that there has been no adequate theory of mystical states and their relationship to the factors which produce them. Consequently a theory of mystical states based on Charles Tart’s systems model of consciousness is proposed. This theory suggests how (...) identical states of consciousness can be induced by very different means, including contemplative practices and chemical substances, and yet have different after-effects. Taken together, these ideas lead to the cautious conclusion that some psychedelics can induce genuine mystical experiences sometimes in some people, and that the current tendency to label these chemicals as entheogens may be appropriate.
