“Seth material” search engine (Jane Roberts)

The organization however is, biologically speaking, artificial and learned. It is no less rigid for that reason. This organizational structure of perception can be broken up, as recent LSD experiments certainly show. This can be dangerous, however. The fact that this does occur shows that the systems of perception are not a part of over-all structure biologically, but learned secondary responses. It is disturbing to the whole organism, however, to break up the strong pattern of usual perception. Inner stability of response is suddenly swept away. Changes that are not yet known occur within the nervous system under these circumstances, both electromagnetic and chemical.

The inner senses alone are equipped to process and perceive other reality systems. Even the distortions can be kept at a minimum with training. Indiscriminate use of the psychedelic drugs can severely shake up learned patterns of response that are necessary for effective manipulation within physical reality; break subtle connections and you disturb electromagnetic functions. Ego failure can result.
