To learn and to do!--this is the soul's work here below. The soul grows as truly as an oak grows. As the tree takes the carbon of the air, the dew, the rain, and the light, and the food that the earth supplies to its roots, and by its mysterious chemistry transmutes them into sap and fibre, into wood and leaf, and flower and fruit, and color and perfume, so the soul imbibes knowledge and by a divine alchemy changes what it learns into its own substance, and grows from within outwardly with an inherent force and power like those that lie hidden in the grain of wheat. The soul hath its senses, like the body, that may be cultivated, enlarged, refined, as itself grows in stature and proportion; and he who cannot appreciate a fine painting or statue, a noble poem, a sweet harmony, a heroic thought, or a disinterested action, or to whom the wisdom of philosophy is but foolishness and babble, and the loftiest truths of less importance than the price of stocks or cotton, or the elevation of baseness to office, merely lives on the level of commonplace, and fitly prides himself upon that inferiority of the soul's senses, which is the inferiority and imperfect development of the soul itself. To sleep little, and to study much; to say little, and to hear and think much; to learn, that we may be able to do, and then to do, earnestly and vigorously, whatever may be required of us by duty, and by the good of our fellows, our country, and mankind,--these are the duties of every Mason who desires to imitate the Master Khūrūm. The duty of a Mason as an honest man is plain and easy. It requires of us honesty in contracts, sincerity in affirming, simplicity in bargaining, and faithfulness in performing. Lie not at all, neither in a little thing nor in a great, neither in the substance nor in the circumstance, neither in word nor deed: that is, pretend not what is false; cover not what is true; and let the measure of your affirmation or denial be the understanding of your contractor; for he who deceives the buyer or the seller by speaking what is true, in a sense not intended or understood by the other, is a liar and a thief. A Perfect Master must avoid that which deceives, equally with that which is false. Let your prices be according to that measure of good and evil which is established in the fame and common accounts of the wisest and most merciful men, skilled in that manufacture or commodity; and the gain such, which, without scandal, is allowed to persons in all the same circumstances. In intercourse with others, do not do all which thou mayest lawfully do; but keep something within thy power; and, because there is a latitude of gain in buying and selling, take not thou the utmost penny that is lawful, or which thou thinkest so; for although it be lawful, yet it is not safe; and he who gains all that he can gain lawfully, this year, will possibly be tempted, next year, to gain something unlawfully.
