You know, in the case of most of us, the mind is noisy, everlastingly chattering to itself , soliloquizing or chattering about something, or trying to talk to itself, to convince itself of something; it is always moving, noisy. And from that noise, we act. Any action born of noise produces more noise, more confusion.
People say the effect is only on the mind. It is no such thing. The effect is on the body, too. Little as we know about the way in which we are affected by form, by colour, and light, we do know this, that they have an actual physical effect. Variety of form and brilliancy of colour in the objects presented to patients, are actual means of recovery.
There is a fountain of youth: it is your mind, your talents, the creativity you bring to your life and the lives of people you love. When you learn to tap this source, you will truly have defeated age.
