DOORS OF THE MIND by Michael Bentine 1984 / 221 pages. *****

To quote Michael "The doors of the many mansions of the mind open both ways. They can let you enter other states of consciousness - or they can allow something or someone to enter yours. You should open these doors with care and caution - but first, you must know how to close them. And above all, you must know which doors should be left unopened."
