5893. Two years the famine is in the midst of the land. That this signifies a state of good in the natural mind, is evident from the signification of "years," as being states (see n. 487, 488, 493, 893); from the signification of "famine," as being a lack of good (for "bread" in the spiritual sense is the good of love, and "food" is the good of truth, and therefore "famine" is a lack of good, and "thirst" is a lack of truth); and from the signification of "in the midst of the land," namely, of Egypt, as being the natural mind (see n. 5276, 5278, 5280, 5288, 5301). It is said "in the midst" because the "midst" is the inmost (n. 1074, 2940, 2973), where good is. "Two years" denotes a state of the conjunction of good and truth, because "two" signifies conjunction (n. 5194), here not yet conjunction, because they are two years of famine.
 The case herein is this. There must be truths in the natural mind in order that good may work, and the truths must be introduced by means of the affection which is of genuine love. All things whatever that are in man's memory have been introduced by means of some love, and remain there conjoined with it. So also it is with the truths of faith-if these truths have been introduced by means of the love of truth, they remain conjoined with this love. When they have been conjoined, then the case is as follows. If the affection is reproduced, the truths which are conjoined with it come forth at the same time; and if the truths are reproduced, the affection itself with which they have been conjoined comes forth at the same time. Wherefore during man's regeneration (which is effected in adult age, because previously he does not think from himself about the truths of faith) he is ruled by means of angels from the Lord, by being kept in the truths which he has impressed upon himself to be truths, and by means of these truths in the affection with which they have been conjoined; and as this affection, namely, of truth, is from good, he is thus led by degrees to good.
 That this is so is evident to me from much experience, for I have noticed that when evil spirits have injected evils and falsities, then angels from the Lord kept me in the truths which had been implanted, and thus withheld me from evils and falsities. From this also it was plain that the truths of faith, which have been inrooted by means of the affection of truth, are the plane into which angels work. Wherefore they who have not this plane cannot be led by angels, but suffer themselves to be led by hell, for the working of the angels cannot then be fixed anywhere, but flows through. But this plane cannot be acquired unless the truths of faith have been put into act, and thus implanted in the will, and through the will in the life. It is also worthy of mention that the working of the angels into the truths of faith with man seldom takes place manifestly, that is, so as to excite thought about this truth; but there is produced a general idea of such things as are in agreement with this truth, together with affection. For this working is effected by means of an imperceptible influx, which when presented to the sight appears like an inflowing light, which light consists of innumerable truths in good, which encompass some single thing in the man, and keep him while in truth also in the love of this truth. Thus the angels elevate the mind of the man from falsities, and protect him from evils. But these things are wholly unknown to the man.
