It may not be practically possible to devise and implement an ideal control method for meditation trials, nevertheless it is important to select a strategy that approximates that ideal. The bare minimum criteria for a control process in meditation research should therefore be:
• First, high face validity as a therapeutic/stress management intervention in its own right. It should actually appear to be a credible meditation technique if that is the expectation of participants.
• Second, a process that involves relaxation and reduction of somatic arousal since this is the nearest conventionally understood phenomenon that meditation resembles and from which it needs to be distinguished.
