"This is a very wonderful moment in the candidate’s spiritual life, as was explained by the Master Kuthumi, when accepting a pupil not long ago. He said to him: Now that you have attained the immediate goal of your aspiration, I would exhort you at once to turn your attention to the far greater requirements of the next step. That for which you have now to prepare, the ‘entering upon the stream’ which the Christians call salvation, will be the salient point in the long line of your earthly existences, the culmination of seven hundred lives. Ages ago, by individualization, you entered the human kingdom; in a future which I trust is not remote, you will quit it by the door of Adeptship, and become a Superman; between these two extremes is no point of greater importance than that Initiation towards which you should now turn your thoughts. Not only will it make you safe for ever, but it will admit you to that Brotherhood which exists from eternity unto eternity—the Brotherhood which helps the world. Think then with how great care so wondrous an event should be approached. I would have you keep the glory and the beauty of it constantly before your mind, that you may live in the light of its ideals. Your body is young for so mighty an effort, but you have a rare and splendid opportunity; I want you to take it to the full."
