If you have cultivated your mind well enough to use it at a high level, then you will send out bright and healthy waves. Thousands of people will feel joy through you. Also, if your practice is advanced enough that you can receive others' dark mind waves and surrender them to Buddha, you will liberate their inner sufferings, wash away their dark shades, and illuminate their minds.
