Well, in some ways we're not successful at all. We're destroying our home. That's not a bit successful.

A good mother is protective but not over-protective. She's patient, she's affectionate, she's playful, but above all she is supportive.

Words can enhance experience, but they can also take so much away. We see an insect and at once we abstract certain characteristics and classify it - a fly.

Words are part of our rational selves, and to abandon them for a while is to give freer reign to our intuitive selves.
