"When you have separated yourself from all which is foreign to
your true inner nature, anything foreign in the exterior world
cannot harm you. Your own psychic health is perfect immunity
from whatever is unhealthy on the outside. In this perfect
health you can experience everything that everyone else ex-
periences, but you are never disappointed or frightened. Why?
Because there is nothing in you which corresponds to the exterior
illness, therefore there is no invitation to it to enter. Health
invites only that which is of its own nature. Health invites
health only."
