One of the fundamental principles of Yoga/Qigong practice is that prana (energy, life-force, qi) follows citta (mind, intention, focus). You can experiment with this, right now, by closing your eyes (after you read the rest of this paragraph!), and then placing as much of your attention/focus into one of your hands (say, your left hand) as you can: as you inhale and exhale, think of sending waves of love or kindness or joy (or some other up-lifting quality) into your left hand. Breathe and focus in this way, on your left hand, for a minute or two, or longer
