Yeah, so does a warm bath but doesn't cost nearly as much. Reiki doesn't advertise itself as a "placebo", it advertises itself as -
If a person is depressed and opts for Reiki rather than counseling and medication, it is dangerous.
Huh? Don't know what you are talking about.
The statement is just that, a statement.
A belief, regardless of how strong it is or how many believe does NOT make it real.
Easter Bunny as an example.
Counseling and medication can be dangerous too... depends on the counselor and the medicine.. does reiki really heal anxiety? Without the medicine, neat somebody must have tried it and it worked?
