Hi Jim,
Thanks for your comment. In the case of TM, it is normally categorized in the scientific literature as a focused awareness meditation. Some are beginning to carve out a separate space for it as there is emerging neuroscientific evidence that, not surprisingly, those repeating a mantra or thinking of a mantra repeatedly are also activating the part of the brain associated with motor function (i.e. the lips are moving, or one is thinking about moving one's lips). Yes, it is true you do not 'focus' on the meditation, but the point is that if you deviate from the mantra you return your attention to it, hence the word 'focus.'
Yours, in service,
Jason
