It's true to an extent. Focusing on emitting energy and empty force and such is a sure way to burn yourself out, and burn up all your own energy. It is best to focus on relaxation, peace of mind,naturalness, spirituality and being a good person. Most people will practice for many years to build up a little bit of energy before using it. Spiritual practice however, can acheive high abilities,( although the power manifested will not mean much and have no value in terms of gain or wealth in society, the meaning behind the event when an ability comes out is really special.)
My qigong teacher was talking about wrong methods recently, and some points I remember emphasized was healers who use up their own energy and make themselves sick, and methods which don't use the universal energy flowing always through them.
