Divine substance.

They stood in the twilight of the Coming Dawn, whose feeble rays
prepared them to look upon the True Light, to hear the Living Word,
and yet not die.

In this state they began to perceive the immeasurable differences
which separate the things of earth from the things of Heaven.

_Life_, on the borders of which they stood, leaning upon each other,
trembling and illuminated, like two children standing under shelter in
presence of a conflagration, That Life offered no lodgment to the
senses.

The ideas they used to interpret their vision to themselves were to
the things seen what the visible senses of a man are to his soul, the
material covering of a divine essence.

The departing _spirit_ was above them, shedding incense without odor,
melody without sound. About them, where they stood, were neither
surfaces, nor angles, nor atmosphere.

They dared neither question him nor contemplate him; they stood in the
shadow of that Presence as beneath the burning rays of a tropical sun,
fearing to raise their eyes lest the light should blast them.

They knew they were beside him, without being able to perceive how it
was that they stood, as in a dream, on the confines of the Visible and
the Invisible, nor how they had lost sight of the Visible and how they
beheld the Invisible.
