This morning I attended a 'pilates induction session' - advertised as 30 minutes, it was actually nearer 40, and basically what we learned was how to breathe in the correct way for pilates.
Much concentration was needed to correctly align the feet, spine and neck, to centre the core and to breathe from the diaphragm. I can't claim to have mastered it, but I gave it a good go, and have signed up for eight weeks of beginners classes.
Whilst I don't think there is a 'right' or even a 'Christian' way to pray, meditate or reflect, there seems to be some sort of parallel... (re-)aligning our hearts, minds, bodies and souls, being aware of our own physicality as well as our intellect and spirituality, discovering that it isn't easy, but it is worthwhile... and then maybe metaphorcially 'signing up' for a short course of intentional prayer/meditation/reflection.
Unlike pilates, where progression from 'beginner' to 'intermediate' to 'advanced' is anticipated/expected, spiritual exercise is not about getting better, but I think it probably is about learning to breathe...
