O thou seeker of the Heavenly Kingdom! This world resembles the human body and the Kingdom of God is like the spirit of life. Think how narrow and dark the material world of man is, how afflicted with disease and maladies; but how bright and spacious is His Spiritual World! Through this illustration thou mayest comprehend in what manner is the Spiritual World portrayed in this earthly world and in what degree is its power effected. Though the Spirit is concealed, its power is manifested and clear in the phenomenal world; and so with the Kingdom of God, though it is veiled from the eyes of the ignorant people, to men of perception it is discernable and evident. Therefore, thou must become entirely heavenly that thou mayest forget the earthly conditions and be immersed in the perception of Divinity to such a degree that thou wilt be unconscious of the surrounding material existence.
