4. The Threshold In Nature and In Man

We see, then, what it was men feared in olden times for the pupil who was to be guided into the inner being of the things of the world, into the inner being of Nature. They were afraid lest he be hurt in his soul, through falling into a condition of uncertainty and darkness, a condition comparable, in the realm of soul, with physical faintness. This danger they hoped to avoid by a thoroughgoing discipline of the will. In ordinary life, they said, man must remain on this side of the realm where the dangerous knowledge is to be found; a Guardian holds him back from the region for which he is unfit, thus protecting him from being overcome by faintness of soul. And their description of the experiences the pupil had to undergo if he wanted to cross the Threshold and pass the Guardian correspond exactly to inner experiences of the soul.
