However, on one occasion, several years ago, I was idiot enough to take a dose of LSD. (I did it to please a woman.) I had what is known as a 'bad trip'. It was a very bad trip. I shall not attempt to describe what I experienced on that dreadful and rather shameful occasion. (I will only add: it concerned entrails.) In fact it would be extremely hard, even impossible, to put it properly into words. It was something morally, spiritually horrible, as if one's stinking inside had emerged and become the universe: a surging emanation of dark half-formed spiritual evil, something never ever to be escaped from. 'Undetachable,' I remember, was a word which somehow 'came along' with the impression of it. In fact the visual images involved were dreadfully clear and, as it were, authoritative ones and they are rising up in front of me at this moment, and I will not write about them. Of course i never took LSD again.
