I never have been in a place to do meditation, but I believe music works great for healing us. what you're doing is really a great work to make them relax and free from everything. when I am sad and empty mostly I grab my guitar and play a while till I become ok. that's where I learned the effect of sounds.
I was watching the video, those instruments are really perfect. you made a great ambient in there.
