243. And white garments, that thou mayest be clothed, signifies genuine truths and intelligence therefrom. This is evident from the signification of "white garments," as being genuine truths, for garments signify truths (See above, n. 195), and "white" signifies what is genuine, and is predicated of truths (See above, n. 196); also from the signification of "to clothe," as being to acquire intelligence for oneself therefrom, for by means of genuine truths all intelligence is acquired; for the human understanding is formed to receive truths, therefore it becomes such as the truths are out of which it is formed. It is supposed that understanding is also the ability to reason from thought and to speak from falsities, and to confirm falsities by many arguments; but this is not understanding, it is only a faculty granted to man with the memory to which it is adjoined, and of which it is an activity. Yet by means of this faculty the understanding is born and formed, so far as man receives truths from affection; but genuine truths it is not possible for any man to receive from affection except only from the Lord, since they are from Him; consequently, to receive understanding, or to become intelligent, is not given to any man, except only from the Lord, but it is given to everyone who applies himself to receive (according to what was said above, n. 239. This, therefore, is signified by "I counsel thee to buy of Me white garments, that thou mayest be clothed."

8051. 'And nothing made with yeast shall be eaten' means that they shall not make anything that has been falsified their own. This is clear from the meaning of 'eating' as making one's own, dealt with in 3168, 3513 (end), 3596, 4745; and from the meaning of 'yeast' as falsity, dealt with in 2342, 7906, so that 'something made with yeast' is something falsified. So far as making falsity and making something falsified one's own are concerned, it should be recognized that no falsity as such or anything falsified as such can be made his own by anyone who is governed by good and therefore wishes to know the truth, only by someone who is ruled by evil and therefore has no wish to know the truth. The reason why one who is governed by good and therefore wishes to know the truth cannot make falsity as such his own is that he thinks in a proper way about God, about God's kingdom, and about spiritual life, and therefore uses falsity in such a way that it is not at odds with them but somehow in agreement. Thus he softens it, and none of its harshness or hardness enters his ideas. If this were not so scarcely anyone could be saved, for falsities are more prevalent than truths. Yet it should be recognized that people governed by good also have a love of truth, and therefore in the next life, when instructed by angels, they cast falsities aside and embrace truths. They do this according to the degree of the love of truth they had in the world.
