A pure and good life is far better for the breathing. Do not let tranquillity be disturbed, and the rhythm of the breath will keep regular; the mind will keep in good condition, and the body healthy. Do not be too attached to anything in the world; do not be a slave to anything. Be beyond all desires. Observe the law of cleanliness, the law of balance, doing good to others, having good wishes, good thoughts, keeping a high ideal, and always wishing to attain the ideal. By doing these things the breath itself will become fixed in the same mold.
