On this Short Path he searches into the meaning of Being, of being himself and of being-in-itself, until he finds its finality. Until this search is completed, he accepts the truth, passed down to him by the Enlightened Ones, that in his inmost essence he is Reality. This leads to the logical consequence that he should disregard personal feelings which continue from past tendencies, habits, attitudes, and think and act as if he were himself an enlightened one! For now he knows by evidence, study, and reflection that the Overself is behind, and is the very source of, his ego, just as he knows by the experience of feeling during his brief Glimpses. Bringing this strong conviction into thought and act and attitude is the "Heavenly Way" [or "As If"] exercise, a principal one on the Short Path.
He pretends to be what he aims to become: thinks, speaks, acts, behaves as a master of emotion, desire, ego because he would be one. But he should play this game for, and to, himself alone, not to enlarge himself in others' eyes, lest he sow the seed of a great vanity.
