8521. 'And it was like coriander seed, white' means the truth within it, that it was pure. This is clear from the meaning of 'seed' as the truth of faith, dealt with in 255, 1940, 2848, 3038, 3310, 3373. 'Coriander seed' is mentioned because it is white; for 'white' has reference to truth, and in addition truth is represented as being white, 3301, 3993, 4007, 5319. The good of truth, meant by 'the manna', is being described now, both the essential nature of the truth in that entity and the essential nature of the good in it. The essential nature of the truth is described by the statement that it was 'like coriander seed, white' and the essential nature of the good by the statement that 'the taste of it was like that of a cake with honey'. The good of truth, which is good as it exists with those who belong to the Lord's spiritual kingdom, is entirely different from good as it exists with those who belong to the Lord's celestial kingdom.
[2] The good of truth existing with those who belong to the spiritual kingdom has been implanted in the understanding part of the mind; for in that part the Lord fashions the new will, which exists in a person when he has the will to act in accord with the truth he has absorbed from the teachings of his Church. And when he wills and does that truth it becomes good residing with him, which is called spiritual good, and also the good of truth. He indeed believes that this is positively the truth, because he has faith in what he has been taught. But he has no perception to see for himself whether it is the truth apart from that which he seems to himself to have as a consequence of having proved it for himself, partly from the sense of the letter of the Word and partly from the misconception that lend support to a preconceived notion. He fails however to consider that nothing, not even actual falsity, is incapable of receiving proof that makes it look like the truth, 4741, 5033, 6865, 7012, 7680, 7950. So it is that all people without exception, including Socinians and also the Jews themselves, believe that their doctrines are the truth.
All this shows the essential nature of the truth that is converted into good with very many members of the Church. None among them can see whether a teaching of their Church is true except those who have an affection for truth for the sake of useful services in life. Those who have this end in view are enlightened by the Lord constantly, not only while they live in the world but also afterwards. They alone are the ones who are able to receive truth, for the Lord leads them by means of good, and through that good He enables them to see truth and so believe it. All this demonstrates the origin and nature of good as it exists with those belonging to the Lord's spiritual kingdom. But good as it exists with those belonging to the Lord's celestial kingdom has been implanted not in the understanding part of the mind, but in the will part. Those with whom this good resides know from inward perception received from the Lord whether something is true. Regarding good as it exists with the one and as it exists with the other, and the difference between them, see 2046, 2088, 2227, 2669, 2715, 2718, 3235, 3240, 3241, 3246, 4138, 4493, 5113, 6500, 6865, 7233, 7977, 7992.
