7902. 'You shall eat unleavened bread' means the assimilation by good of truth purified from falsity. This is clear from the meaning of eating as making one's own or assimilating, dealt with in 2187, 2343, 3168, 3513 (end), 3596, 4745 (the assimilation of truth by good is meant because truth is assimilated by good, and good - as shown in various places already - derives its specific quality from truth; therefore to make truth one's own truth must be assimilated by good, and to make good one's own good must be conditioned by truth); and from the meaning of what is 'unleavened' as truth purified from all falsity, dealt with in 2342. As regards truth purified from all falsity, it should be recognized that pure truth cannot ever reside with anyone. It cannot both because falsity issues constantly from the evil present and firmly fixed within him, and because the truths are interconnected; therefore if one falsity is present, worse still if a number are present, the actual truths remaining are consequently defiled and have something of falsity in them. But truth is said to be purified from falsity when a person can be preserved by the Lord in the good of innocence. Innocence consists in acknowledging that nothing but evil resides in oneself and that any good comes in from the Lord, and also in believing that one neither knows nor perceives anything, including the truth of faith, if left to oneself, only with the Lord's help. When this is a person's state falsity can be removed from him and truth instilled by the Lord. This state is what is meant by 'unleavened bread' and also by the eating of the Passover lamb.

3513. 'And I will eat' means in that way making it its own. This is clear from the meaning of 'eating' as being made one's own, dealt with in 2187, 2343, 3168, 3503. It is made its own when, by means of forms of pleasantness and delight, truths, that is, cognitions of good and truth, are instilled into the natural; and when these truths are allied to the good in the natural, communication is effected with the truth and good of the rational and so with the rational itself. It is this communication that the expression 'being made one's own' is used to describe, for those truths belong to the rational within the natural. Indeed truths in the rational are related to those in the natural in the way that individual parts are related to their general wholes. It is well known that a general whole is the product of its individual parts and that without the individual parts no general whole can be produced. It is the general whole produced from the individual parts belonging to the rational that is manifested in the natural. And being a general whole it takes a different form, doing so according to the order of the individual constituent parts, and so according to the form that results. If it is the more specific and the consequent individual parts of celestial good and spiritual truth that give form to the general whole within the natural, then it is a celestial and spiritual form that is presented, and something of heaven is represented as a kind of image in the specific parts constituting the general whole. But if the more specific and the individual parts which give form to the general whole within the natural do not consist of good and truth but of evil and falsity, something of hell is in that case represented as a kind of image in the specific parts constituting the general whole.

[2] Such are the things meant by eating and drinking in the Holy Supper, where again eating and drinking mean making one's own; that is to say, 'eating' means making good one's own and 'drinking' making truth one's own. If good, that is to say, love to the Lord and charity towards the neighbour, gives form to the internal or rational man, and by way of this rational man gives form to a corresponding external or natural man, the person becomes in particular and in general an image of heaven, and therefore an image of the Lord. But if contempt for the Lord and for the good and truth of faith, and hatred towards the neighbour give form to the rational man, the person becomes in particular and in general an image of hell - the more so if at the same time he eats and drinks in a holy manner, for profanation then results. Consequently people who eat and drink worthily make eternal life their own, whereas those who do so unworthily make [eternal] death their own.
