There is a bridge between time and eternity

There is a bridge between time and eternity;
and this bridge is the spirit of man. Neither
day nor night cross that bridge, nor old age,
nor death, nor sorrow. Evil or sin cannot
cross that bridge, because the world of spirit
is pure. This is, why when this bridge has
been crossed, the eyes of the blind can see,
the wounds of the wounded are healed, and
the sick man becomes whole from his sick-
ness. To one who goes over that bridge, the
night becomes like unto day; because in the
world of the spirit there is a Light which is
Everlasting.
