4. The Threshold In Nature and In Man

It was told how, when the pupil draws near the Threshold, he immediately has a feeling of uncertainty. If he has been sufficiently prepared, he is able to stand upright in the realm which would otherwise make him giddy; he passes the Guardian of the Threshold and, by virtue of the powers of his soul, enters into the spiritual world—which the Guardian would otherwise not allow him even to behold. But he must be able also to stay in the spiritual world with full consciousness. For the tremendous experiences that await him there call for strength and not for weakness, and if he were to let go, these experiences would have a shattering effect on his whole organisation; he would suffer grievous harm.
