The outer world is what we wake up to every morning

of our lives, is the place where… we must try to make our living.

In the inner world there is neither work nor monotony.

We visit it only in dreams

and musings, and its strangeness

is such that we never find the same world on two successive occasions.

What wonder, then, if human beings in their search for the divine have generally preferred to look within!

Aldous Huxley, The Doors of Perception
