What comes under the heading of psychic practices
'Abdu'l-Baha has warned us against; but any form of auto-suggestion or
hypnotism which is used by medical science and by properly qualified physicians
we are free to take advantage of, if we feel that the doctor using such
practices is qualified and will not abuse his rights.
