William James, The Varieties of Religious Experience…
“ By means of such discipline the mental horizon can be flooded with the sunshine of beauty, wholeness, and harmony. To inaugurate pure and lofty thinking may at first seem difficult, even almost mechanical, but perseverance will at length render it easy, then pleasant, and finally delightful.“The soul's real world is that which it has built of its thoughts, mental states, and imaginations. If we will, we can turn our backs upon the lower and sensuous plane, and lift ourselves into the realm of the spiritual and Real, and there gain a residence. ”
