Human intent as it affects health

I believe that intent has a great deal of effect on health..patterns of thinking and behavior determine much in our overall state of our own health. In terms of intent of a practitioner, I think it is equally important. The state of our inner life, our heart, can be transmitted and felt by those we work with and it is important to strive for a peaceful and compassionate state of being, both towards ourselves and others. Will an acupuncture point work if I am worrying how I'll pay my rent? I think it will have an effect, especially if the persons own healing intent is strong, but inserting needles while pent up and worried also may have an effect of it's own, maybe on my patient, maybe on me as well. I think, overall, the most effective and enjoyable treatments I have observed and received have been at the hands of a calm, caring and focused practitioner.
