A person may be sitting still, and for a few moments he falls asleep, and by a voice, or by a symbol or by actual sight, something is shown to him. A poem is revealed to a poet, music to a musician, or a message, or an object is revealed. It is not only the mystics who experience this, but musicians, poets, artists, inventors, the people who have made the great factories. The musicians, poets, artists, experience this, and the mystics after their development. This is sometimes called inspiration.
