Only when the lamp of search, of earnest striving, of
longing desire, of passionate devotion, of fervid love, of rapture, and
ecstasy, is kindled within the seeker's heart, and the breeze of His
loving-kindness is wafted upon his soul, will the darkness of error be
dispelled, the mists of doubts and misgivings be dissipated, and the lights of
knowledge and certitude envelop his being. At that hour will the mystic Herald,
bearing the joyful tidings of the Spirit, shine forth from the City of God
resplendent as the morn, and, through the trumpet-blast of knowledge, will
awaken the heart, the soul, and the spirit from the slumber of negligence. Then
will the manifold favours and outpouring grace of the holy and everlasting
Spirit confer such new life upon the seeker that he will find himself endowed
with a new eye, a new ear, a new heart, and a new mind. He will contemplate the
manifest signs of the universe, and will penetrate the hidden mysteries of the
soul. Gazing with the eye of God, he will perceive within every atom a door
that leadeth him to the stations of absolute certitude. He will discover in all
things the mysteries of divine Revelation and the evidences of an everlasting
manifestation.
