The Tao Teh King: A Short Study in Comparative Religion, by C. Spurgeon Medhurst, , at sacred-texts.com
Who knows men has discernment; who knows himself has illumination. 1
Who overcomes men has strength; who overcomes himself has determination. Who knows contentment has wealth. 2
Who acts vigorously has will. 3
Who never departs from his base, endures long; he dies, but does not perish; he lives eternally. 4
58:1 The discernment which gives knowledge of men by providing points for comparison produces the illumination which leads to self-knowledge. Su Cheh says that one can never know himself until he puts all distinctions on one side; a statement supported by Porphyry, who in his treatise on sensation says that the mind only sees itself when it regards objects, as ''the mind embraces everything, and all that exists is nothing but the mind, which contains bodies of all kinds." See Encyc. Britt., 9th edit., vol. i., p. 461. Comp. also the teachings of Plotinus.
"I, the imperfect, adore my own perfect."—Emerson in his essay on "The Oversoul."
58:2 "The Princely Man is contented even in poverty."—Chinese proverb. See Phil. iv. 11.
58:3 "When I seek nothing from without, but vigorously attend to myself there is nothing which can interfere with my will."—Su Cheh.
