I definitely agree with Briggi that the whole spectrum of yoga postures is recommended. in my own experience, the most quiet and lucid meditation periods have been after a well balanced series of asanas. For me it is also a sequence which is matched to the energy of my body at that time - not too vigorous, not to easy. Over the long term, i have noticed that the practice of hatha yoga does open up the physical and energy bodies to enable easier sitting, and that as the energy fields and channels clear, the mind becomes clear as well.

I do all the movements my body needs to do to unwind/unkink/reinform from all the bad habits I've used during the day so that my alignment and breathing is better before mediation (not that I meditate for an hour, except when I go to Quakers).

I sit at a computer for my job all day (too many of us do), and often in cross-legged (this is my natural seated position - can do forever), so I, for example, do a lot of psoas-opening, back strectching, twists, side openers, core concentration, inversions!, standing (to open the front of the legs) and WALK alot. I then often will meditate STANDING or in constructive-rest position (on my back with my knees up).

My BEST suggestion - come to the mat and ask your body what it wants to do before you mediatate. "What do you need, what do you want, my dear body?" You'll find that answer different everyday, perhaps, maybe somedays wanting to meditate first.

Huzzah! to you.
