Hello everyone, I'm new to daoism and I was searching for some systems that I could start practicing.   I heard I can practice all of these alone because they are safe.   So, here are the systems I googled into and I want your opinion on which one can get more healing benefits.   First of all I want to heal myself and build more jing, I don't want supernatural powers or spiritual enlightenment at the moment, I just want to be a healthy person above average, if possible. If someone can help me, please, I will be very grateful!
