meditation garden

I want to make a meditation garden. I will probably wind up with two eventually, because I eat breakfast and meditate while looking at my patio plants (pretty but not organized), but when I get home from work I sit at the back of the yard by the pond and meditate. There is a small bed around the pond with nothing in yet except nutgrass. I can't decide where to start. Part of my problem is that when I think meditation garden I think of an enclosed space. But the space I have to work with is small and anything big enough to make it feel enclosed will shade other things too much that need lots of sun. I have started a privacy hedge at the back of the lot (about 15 ' from the pond) but it'll be some time before they get big enough to provide much privacy. I need some inspiration. And of course I have not much money.
