" The great point in learning to live the spiritual life is to live naturally. As closely as possible we must follow the broad, clear lines of the natural life. And there are three things especially which it is necessary for us to keep continually in view. The first is that the organism contains within itself only one-half of what is essential to life; the second is that the other half is contained in the Environment; the third, that the condition of receptivity is simple union between the organism and the Environment. "
