But for an honour so great as this mere ordinary goodness will not suffice. True, a man must be good first of all, or it would be hopeless to think of using him, but in addition to being good he must be wise and strong. What is needed is not merely a good man, but a great spiritual power. Not only must the candidate have cast aside all ordinary weaknesses but he must have acquired strong positive qualities before he can offer himself to Them with any hope that he will be accepted. He must live no longer as a blundering and selfish personality, but as an intelligent ego who comprehends the part which he has to play in the great scheme of the universe. He must have forgotten himself utterly; he must have resigned all thought of worldly profit or pleasure or advancement; he must be willing to sacrifice everything, and himself first of all, for the sake of the work that has to be done. He may be _in_ the world, but he must not be _of_ the world. He must be careless utterly of its opinion. For the sake of helping man he must make himself something more than man. Radiant, rejoicing, strong, he must live but for the sake of others and to be an expression of the love of God in the world. A high ideal, yet not too high; possible, because there are men who have achieved it. When a man has succeeded in unfolding his latent possibilities so far that he attracts the attention of the Masters of the Wisdom, one of Them will probably receive him as an apprentice upon probation. The period of probation is usually seven years, but may be either shortened or lengthened at the discretion of the Master. At the end of that time, if his work has been satisfactory, he becomes what it commonly called the accepted pupil. This brings him into close relations with his Master, so that the vibrations of the latter constantly play upon him, and he gradually learns to look at everything as the Master looks at it. After yet another interval, if he proves himself entirely worthy, he may be drawn into a still closer relationship, when he is called the son of the Master. These three stages mark his relationship to his own Master only, not to the Brotherhood as a whole. The Brotherhood admits a man to its ranks only when he has fitted himself to pass the first of the great Initiations.
