How do you cast a mind control spell?

There may be such spells out there somewhere. I have never encountered any to date and I have been studying for decades.

What I feel should be pointed out at this time is that NO responsible or ethical practitioner of magic would teach such spells to you. It is not the habit of those of us who work with magic to undertake ANYTHING that would be detrimental to another. Addendum: There are some who feel that if it can be PROVEN to be less harmful than not interfering, that it is still ethical. However, it is an extremely delicate issue.
