Most people live...in a very restricted circle of their potential being.

They make use of a very small portion of their possible consciousness, and of
their soul's resources in general, much like a man who, out of his whole bodily organism, should get into a habit of using only his little finger.
William James, The Varieties of Religious Experience

The very same Erin who has written some delightful posts on wandering in Spain and on life.
