Is supersensory development the same thing as metaphysical and psychic development?

Yes, Culdians prefer to use the words ‘supersensory’ or ‘metaphysical’ rather than psychic, as the latter has become associated in the minds of many people with gullibility, charlatanism and commercialism. It is unfortunate that it has been so tainted, because many sincere, genuine and non-gullible people have accepted the reality of psychic phenomena.
