Further particulars respecting love and its essence and quality, may be known from what has been said and shown above, concerning good and truth; also from what has been said and quoted concerning the will and the understanding; and also from what has been said and quoted concerning the internal and the external man; because all things which are of the love refer themselves either to goods or to evils; and so also all things which are of the will: and since the two loves of heaven open and form the internal spiritual man; but the two loves of hell close and destroy it. Hence applications may be made and conclusions drawn respecting the quality of love in general and particular.
