Excellent reply Gianni. How could a reply be better if it come from a place of caring?

frances it is a matter of good, better, best. Yes the quality and quantity of your thoughts will influence the progression along good, better, best. However, it is more important to come from a place of Love, Kindness and Caring. Then to form your thoughts with positive and confident thoughts.
Your mind may wander, but it will wander less as your practice improves and grows. Remember to focus on the health and not the ailment. Start a meditation, if a clear objective. It could be a request for help with a problem. It could be seeing yourself (or someone else) free of the problem. Then forget it. Release it to the universe to guide the energy towards your needs as you immerse yourself in the meditation.
Start in the right place, set your course, and have faith and confidence it will be achieved. That is one of the places you Master can help.
You are perfection.
