Feelings aroused by the touch of someone's hand, the sound of music, the smell of a flower, a beautiful sunset, a work of art, love, laughter, hope and faith - all work on both the unconscious and the conscious aspects of the self, and they have physiological consequences as well.

This quote is talking about the power of emotions, which is the way that people feel and experience different sensations and experiences. It states that when someone touches your hand, hears music, smells a flower, or experiences other positive things such as love, laughter, hope, and faith, it can affect both your conscious (the part of your brain that is aware of your actions and thoughts) and unconscious (the part of your brain that operates without you realizing it) minds. It also states that these positive feelings have physiological consequences, which means that it will do something to your body, such as making your heart beat faster or releasing hormones that make you feel more relaxed.
