If I remember correctly there is a term like “With a foot in either camp.” Well, we know that we are “In this world, not of this world.” so I have associated my left leg with the Reality and my right leg with the Earthly world* and when I have wished to move away from menting** and to thought I have actually transferred my weight to my left foot with the desired result.
I pass this on for what it is worth to anyone.
* This is probably due to my being right handed. It may be that, in the case of left-handers, the association is reversed. Let us know.
** Menting? See entry New Words Coined.
