There is a bridge between time and Eternity; and this bridge is Atman, 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 Sprit is pure. This is why then 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 sickness.
To one who goes over that bridge, the night becomes like unto day; because in the worlds of the Spirit there is a light which is everlasting.
