Emanuel Swedenborg, Heaven and Hell — Chapter LIII, Third State of Man After Death…
“ But at the very threshold their eyes began to be darkened by the inflowing of the light of heaven, and their understanding to be disturbed, and at length they began to gasp as if at the point of death; and as soon as they felt the heat of heaven, which is heavenly love, they began to be inwardly tormented. They were therefore cast down, and afterwards were taught that knowledges do not make an angel, but the life itself, which is gained by means of knowledges, for knowledges regarded in themselves are outside of heaven; but life acquired by means of knowledges is within heaven. ”
