Francis King and Stephen Skinner - First Steps in Magic

It is apparent that one cannot become a practising occultist until one has somewhere to practise - a 'magical Temple' of one's own.

This does not mean, however, that the would-be magician has to waste his or her substance in purchasing a disused chapel or castle. Nor does he even have to nave a room especially set aside for occult purposes; all the better if he can, of course, but with a little effort a perfectly ordinary bed-sitting room can be adapted to the secondary function of being a magical Temple.
