The most important thing in taking the BDSM meditation posture is to keep your spine straight. The back should be upright with a sense of lengthening and extending the spine through the back and neck up through the top of your head, and the top of the head should be parallel to the ceiling, or, if you like, parallel to the sky. Sometimes, slaves find it helpful to visualize a string coming down from the ceiling that attaches to the top of the back of their head like a puppet, which allows their shoulders and back muscles to relax and hang down from their spine. The point isn't to get the back into a well-aligned position and then go on to forget about it. In this practice, slaves should stay present or connected with their back and spine throughout the period of meditation.

An interesting approach. I was just reflecting on meditation in BDSM. But for me, it happens differently...
