Not everyone is suited to all meditation techniques. Some people do really well lying down or sitting still, and other people are suited to meditation that occurs during repetitive movement. Some people use both, depending on the circumstances and what they prefer.
So here is a bit of information about moving meditations; which are the kind that I prefer to do. Having a panic disorder forced me to look outside of what was the norm (at the time that I was researching meditation) for other ways to still my mind, and I found that for me, walking, repetitive art strokes, and even rocking were more conducive to me reaching a calmer, focused place; than simply forcing my body to be still.
