9399. And Moses took the blood, and sprinkled it on the people. That this signifies adaptation to the reception of man, is evident from the signification of "the blood of the sacrifice," as being the Divine truth that proceeds from the Lord (of which above, n. 9393); and from the signification of "sprinkling on the people," as being adaptation to the reception of man; for by "sprinkling" is signified flowing in, thus adapting. For the Divine truth which is from the Lord is continually flowing in with man, and forms his understanding; and if you will believe it, without this continual influx of the truth Divine that proceeds from the Lord a man can perceive and understand nothing whatever. For the Divine truth that proceeds from the Lord is the light which lights up the mind of man, and makes the internal sight, which is the understanding; and as this light continually flows in, it adapts everyone to receive. But they who receive are they who are in the good of life; and they who do not receive are they who are in evil of life. Nevertheless the latter, like the former, have the capacity of perceiving and understanding, and also the capacity of receiving, insofar as they desist from evils. These things were signified by the half of the blood which Moses sprinkled on the people.
 (That the Divine truth which proceeds from the Lord is the light which lights up the mind of man, and makes his internal sight, which is the understanding, see n. 2776, 3167, 3195, 3636, 3643, 3993, 4405, 5400, 8644, 8707.) This also is meant in John:
That was the true light, which lighteth every man that cometh into the world. He was in the world, and the world was made by Him, but the world knew Him not (John 1:9, 10);
the subject here treated of is the Word, which is the Divine truth that proceeds from the Lord.
 That every man in the world who is of sound reason has the capacity of understanding truth Divine, and consequently the capacity of receiving it, insofar as he desists from evils, has been given me to know by much experience. For all in the other life, without exception, both the evil and the good, can understand what is true and what is false, and also what is good and what is evil; but although the evil understand what is true and good, they nevertheless do not desire to understand, because their will and the evil therein make resistance. And therefore when they are left to themselves, they nevertheless sink back into the falsities of their evil, and hold in aversion the truth and good which they had understood. The case had been the same with such persons in the world, where they had rejected truths, although they could understand them. From this experience it has become evident that the Divine truth which proceeds from the Lord is continually flowing into human minds and adapting them to receive it, and that it is received in the proportion that the evils of the loves of self and of the world are desisted from.
