10122. 'And a young bull of sin [offering] you shall offer daily at propitiations' means the continuous removal of evils and consequently of falsities in the natural man by means of the good of innocence from the Lord. This is clear from the meaning of 'a young bull' as the good of innocence in the natural man, dealt with in Arcana Coelestia 9391, 9990; from the meaning of 'sin' as purification from evils and consequently falsities (by 'sin' a sacrifice for sin should be understood, Arcana Coelestia 10039, and 'a sin sacrifice' means purification from evils and falsities, Arcana Coelestia 9938, 9990, 10022, 10053), the reason for saying 'the removal' of evils and consequently of falsities being that the evils and falsities with a person are not cast out, only removed or moved back, see the places referred to in Arcana Coelestia 10057; from the meaning of 'daily' or each day as continuously; and from the meaning of 'propitiations' as reception of the good of love and truth of faith from the Lord after the removal of evils and consequently of falsities, dealt with in Arcana Coelestia 9506.
 The words 'removal of evils and consequently of falsities' are used because all falsities exist as a result of evil; therefore to the extent that evil is removed falsities are removed. The situation is that all things in heaven have connection with good and consequently with truth, and all things in hell with evil and consequently with falsity. The same is so in people. All the things with a person that come from heaven have connection with good and truth, and all those that come from hell have connection with evil and falsity. Or what amounts to the same thing, all things with a person which originate in the Lord have connection with good and truth, but all that originate in the person himself have connection with evil and falsity. Since good and truth or falsity and evil are what everything throughout creation has connection with, and the human being is the place where they are received, a person has two mental powers to receive them. One is called the will and the other the understanding, the will being what receives good or evil, and the understanding what receives truth or falsity. The will formed by the Lord, also called the new will, receives good, while the understanding formed by the Lord, also called the new understanding, receives truth. But the will properly a person's own, also called the old will, receives evil, and the understanding properly a person's own, also called the old understanding, receives falsity. A person possesses the old will and understanding through being born from his parents, but he comes to have the new will and understanding through being born from the Lord, which happens when he is being regenerated. For when being regenerated a person is conceived anew and is born anew.
 The human being has been created in such a way that will and understanding may make one, so that these two together may constitute a whole person. For a person has been given an understanding to comprehend truth, yet to the end that truth may be implanted in his will and become good. And to the extent that it is integrated into the will it has a place in that person; for the will is the inmost part of a person and is the inner being of his life, whereas the understanding is more external and derives its being from the will. For what a person wills he loves, and what he loves gives him a feeling of delight and is therefore called good by him. The understanding lends support to and strengthens it by means of reasons which it calls truths. So it is that will and understanding in reality make one. The situation may indeed seem to be other than this, as when a person understands the truth and yet wills what is evil; even so, when he is left alone to think for himself, what he understands is in full agreement with what he wills, that is, what he loves.
 The fact that a person who wills what is evil can nevertheless speak what is true and also do what is good is due to hypocrisy, which uses truth and good as means to its own ends. If those means are taken away from such a person and he is left in freedom, he plunges, under the influence of his unrestrained will, into evils, and uses his power of understanding to defend them. This is above all evident from the same kind of people in the next life. There everyone comes into a state [of life] akin to that of his will, and then people in whom a new will has not been formed by the Lord plunge into evils of every kind and think such things as endorse evils, even though what they had spoken and what they had done in the world had been completely different from this. For it is a law of Divine order that will and understanding should form a mind at unity, thus a person at unity, consequently that the entire person should be either in heaven or in hell and not hanging between the two, that is, with his eye looking towards the things of heaven and his heart set on those of hell. By heart is meant the will, and by eye the understanding.
