For only Eternal God knows the eternity of His light which proceeds from Him, and I speak
frankly to those to whom His immeasurable, immense and incomprehensible greatness has been
disposed to grant revelations through long, melancholy inspiration, that with the aid of this
hidden element manifested by God, there are two principal factors which make up the prophet's
intelligence.
The first is when the supernatural light fills and illuminates the person who predicts by astral
science, while the second allows him to prophesy through inspired revelation, which is only a
part of the divine eternity, whereby the prophet comes to assess what his divinatory power has
given him through the grace of God and by a natural gift, namely, that what is foretold is true
and ethereal in origin.
