It can be therapy, but it has to be receptive. Chi is like foreplay for the spirit realm. Your brain might be very ready for my Chi to enter your body, but if the Chi is just broadcast towards your body without the proper prep foreplay, it won't get that deep into your body, and in turn will experience what I like to refer to as "chaffing". All sides of my Chi weren't readily accepted into your body, and in turn the outter area of my Chi has been rubbed raw. You must begin your Chi broadcast with very positive field energy stating how wonderful the other persons Chi field looks at that time, that their Chi field hasn't let themselves go, and similar approaches. With practice, and knowing what to broadcast, it can work great!
