The Tao Teh King: A Short Study in Comparative Religion, by C. Spurgeon Medhurst, , at sacred-texts.com
The world may be known without going out of doors.
The heavenly way (Tao) may be seen without looking through the window. 1
The further one goes the less one knows.
Hence the Holy Man arrives without traveling; 2 names without looking; accomplishes without action. 3
By concentration on this inner universe, by meditation on the Higher Self, by unselfish obedience to the holy vision, the world may be known without going out of doors. The unselfish, who are devoid of self-seeking, who subordinate the finite to the Universal Will, may follow this Divinity within wherever it leads. "If ye abide in my word, then are ye truly my disciples; and ye shall know the truth, and the truth shall make you free." The pure in heart, or the single-minded, "see God."
80:1 Su-cheh writes, ''Spirit is universal, knowing nothing of either near or far, ancient or modern. It is thus that the Sage knows everything without going from the door, or looking through the window. Men of the present day are limited by matter, the spirit within them is limited by ears and eyes, thus they are thrown into confusion by desires and by their bodies; thus mountains and rivers become barriers; they know nothing excepting what their eyes see, or their ears hear, and in this way even such trifles as doors and windows obstruct them. Are you not aware that the Sage having recovered his original nature is satisfied? Why desire to go abroad to search? The farther you go the less you will know." See "The Voice of the Silence," p. 13 (note).
Wang-pi says: "All things have one ancestry; all roads meet at one point; all thought leads to the same conclusion; all religions point to the same goal."
80:2 i.e. he knows intuitively and does not require to go over each point step by step.
