If Savants recieve meditation as it has been implied they will, I think they should NOT kneel when doing so. While empaths are another matter, the kneeling aspect seems to be a remnant of the "religious" aspect of meditation. I would propose that Savants meditate either standing up or sitting, but not kneeling.

If you think about it, in terms of mentalists or monks and such, kneeling isn't really the classical position, but a sitting lotus of some sort. Those are my thoughts on the matter, anyway.
