Could you share some instruction on this? I've found myself discovering this myself and I feel very interested in information on this somebody could already have developed. I don't feel like I have time to learn the entire Chinese medicine but certain instructions on what I can do within me manipulating my attention to reach particular effects could help a lot.
But the best practice I've found is the Secret Smile [1]. By recalling/imagining intensely positive emotions you can prompt your body to recreate them, transforming (or at least diminishing) your current emotional state. It's really no different to having a fantasy. The trick is though that you don't just recall the positive emotions, but you circulate them through your body so they reach every cell, and use deep, relaxed belly breathing to further enhance them. It's a very powerful practice and not only is it useful for higher energetic/meditational practices in its own right, but also teaches you that you don't need to be subject to your emotions - you can use thoughts to change them.

Apparently in Traditional Chinese Medicine they say each organ is associated with a different emotion. Whether you believe it or not, I have recently been surprised by just how pleasurable it feels to massage my internal organs through my abdominal wall. It actually makes me laugh out loud and sends tingles through my body.
