The Silence: What It Is and How To Use It by David V. Bush
There are steps of approach to the Silence. Stillness is one thing and the Silence is another. One may quiet himself physically and not be still, and he may be still without entering the Silence. When one becomes physically and mentally at rest, he is apt to become receptive to psychic influences; and when these are not desired it is advisable to protect oneself while mentally negative. One may affirm his Oneness with God, his being surrounded and protected by the divine Goodness, and may symbolize this by enveloping himself in thought with the white light of love or the mellowed tints of sunshine.
