There is also what is sometimes called a subjective answer to such prayers, the re-action of the prayer on the utterer. His prayer places his heart and mind in the receptive attitude, and this stills the lower nature, and thus allows the strength and illuminative power of the higher to stream into it unchecked. The currents of energy which normally flow downwards, or outwards, from the Inner Man, are, as a rule, directed to the external world, and are utilised in the ordinary affairs of life by the brain-consciousness, for the carrying on of its daily activities. But when this brain-consciousness turns away from the outer world, and shutting its outward-going doors, directs its gaze inwards; when it deliberately closes itself to the outer and opens itself to the inner; then it becomes a vessel able to receive and to hold, instead of a mere conduit-pipe between the interior and exterior worlds. In the silence obtained by the cessation of the noises of external activities, the "still small voice" of the Spirit can make itself heard, and the concentrated attention of the expectant mind enables it to catch the soft whisper of the Inner Self. Even more markedly does help come from without and from within, when the prayer is for spiritual enlightenment, for spiritual growth. Not only do all helpers, angelic and human, most eagerly seek to forward spiritual progress, seizing on every opportunity offered by the upward-aspiring soul; but the longing for such growth liberates energy of a high kind, the spiritual longing calling forth an answer from the spiritual realm. Once more the law of sympathetic vibrations asserts itself, and the note of lofty aspiration is answered by a note of its own order, by a liberation of energy of its own kind, by a vibration synchronous with itself. The divine Life is ever pressing from above against the limits that bind it, and when the upward-rising force strikes against those limits from below, the separating wall is broken through, and the divine Life floods the Soul. When a man feels that inflow of spiritual life, he cries: "My prayer has been answered, and God has sent down His Spirit into my heart." Truly so; yet he rarely understands that that Spirit is ever seeking entrance, but that coming to His own, His own receive Him not.[303] "Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him."[304]
