4. Work as those work who are ambitious. Respect life as those do who desire it. Be happy as those are who live for happiness. Seek in the heart the source of evil and expunge it. It lives fruitfully in the heart of the devoted disciple as well as in the heart of the man of desire. Only the strong can kill it out. The weak must wait for its growth, its fruition, its death. And it is a plant that lives and increases throughout the ages. It flowers when the man has accumulated unto himself innumerable existences. He who will enter upon the path of power must tear this thing out of his heart. And then the heart will bleed, and the whole life of the man seem to be utterly dissolved. This ordeal must be endured: it may come at the first step of the perilous ladder which leads to the path of life: it may not come until the last. But, O disciple, remember that it has to be endured, and fasten the energies of your soul upon the task. Live neither in the present nor the future, but in the eternal.
