67. It shall also be stated briefly how man ascends, that is, is elevated, from the lowest degree to the first. He is born into the lowest degree of the natural world; then, by means of knowledges, he is elevated into the second degree; and as he perfects his understanding by knowledges he is elevated into the third degree, and then becomes rational. The three degrees of ascent in the spiritual world are in man above the three natural degrees, and do not appear until he has put off the earthly body. When this takes place the first spiritual degree is open to him, afterwards the second, and finally the third; but this only with those who become angels of the third heaven; these are they that see God. Those become angels of the second heaven and of the last heaven in whom the second degree and the last degree can be opened. Each spiritual degree in man is opened according to his reception of Divine Love and Divine Wisdom from the Lord. Those who receive something thereof come into the first or lowest spiritual degree those who receive more into the second or middle spiritual degree, those who receive much into the third or highest degree. But those who receive nothing thereof remain in the natural degrees, and derive from the spiritual degrees nothing more than an ability to think and thence to speak, and to will and thence to act, but not with intelligence.
