Qigong is very powerful...and there are many different kinds, including Falun Gong. Usually, it turns out to not be so simple however...I mean 16 CDS does not seem simple to me!
You might want to look into Pal Dan Gum, or the Eight Silken Movements. These are eight VERY SIMPLE exercises. Doing them takes no more than ten minutes, and you can download the instructions for free...but they are very powerful. (It helps if someone can read the instructions to you as you do them the first few times..as there are no pictures. I do remember seeing a site that had pictures, but could not find it today.) These exercises can lift you energisticly, creatively, and emotionally. Check it out!
