Stress Management. From Avoiding Evil:

Picture yourself near a stream.
Birds chirping in the cool, crisp mountain air.
Nothing can bother you here.
No one knows this secret place.
You are in total seclusion from that place called the "world".
The soothing sound of a gentle waterfall fills the air with a cascade of serenity.
The water is so clear that you can easily make out the face of the person whose head you are holding under the water.

There now...Feeling better?

He calls it stress management. I call it behavior modification.
