[2] As for the state of truth within good, this can indeed be described but no one can grasp what it is except those who have celestial perception. People who do not have this perception cannot even have any concept of the joining of truth to good, since for them truth lies in obscurity. Indeed they call the truth that which they have learned from matters of doctrine, and they call good that which is done in accordance with that truth. But those who do have perception have an understanding or mental sight that dwells in heavenly light, and they take delight in truths which are joined to good, just as the eye or physical sight takes delight in flowers growing in gardens and meadows in springtime. And people who have interior perception take delight so to speak in the lovely scent coming from them. Such is the angelic state, and therefore those angels perceive all the differences and all the variations that go with the instillation of truth into good and the joining together of them one within the other. So they perceive immeasurably more than man does, for man does not even know of any such instillation and joining together and that it is in this way that man becomes spiritual.

[3] But so that people may have some concept of this matter a brief statement must be made about it. There are two things which constitute the internal man - understanding and will. To the understanding truths belong and to the will goods, for that which a person knows and understands to be true he calls the truth, and that which he does from the will, and so that which he wills, he calls good. These two abilities must constitute a single unit. This may be illustrated by comparison with the sight of the eye and with the pleasure and delight which is experienced through the use of this sight. When the eye beholds objects it takes pleasure and delight in their form and colour and the resulting beauty which these bring to the objects as a whole and to the individual parts; in short it takes delight in the order or patterns in these. That pleasure and delight does not belong to the eye but to the mind (animus) and its affection. And insofar as a person has any affection for them he beholds them and retains them in his memory. But things which the eye beholds without any affection for them slip away and are not sown in the memory and so made part of it.

[4] From this it is evident that the objects of external sight are implanted insofar as there exists the pleasure and delight that go with affections for them, and that those objects are present in that pleasure and delight. For whenever much the same pleasure or delight occurs such objects return with them; and likewise whenever much the same objects are seen again such pleasure and delight returns with them, though with variations that depend on the states involved. A similar situation exists with the understanding, which is internal sight. The objects of that sight am spiritual and are called truths, for the field in which those objects are active is the memory, and the pleasure and delight associated with that sight is good. So it is good in which truths are sown and implanted. From this one may gain some idea of what the instillation of truth into good is and the joining together of them one within the other, also some idea of what that good is which is the subject here, a kind of good about which angels perceive countless things, whereas man perceives scarcely anything.
