5887. 'And now, do not be grieved' means anxiety in the heart or will. This is clear from the meaning of 'grief' as anxiety, existing indeed in the heart or will. For the words that immediately follow 'do not have any anger in your eyes' mean sadness in the spirit or understanding. The expressions 'in the heart or will' and 'in the spirit or understanding' are used because 'the heart' has reference through correspondence to desires in the will, for it has reference to what is celestial, which is the good of love. But 'the spirit', which is associated with the lungs, has reference to ideas in the understanding, for it has reference to what is spiritual, which is the truth of faith, see 3635, 3883-3896.

3883. THE GRAND MAN AND CORRESPONDENCE - continued IN THIS SECTION THE CORRESPONDENCE WITH THE HEART AND LUNGS
What the Grand Man is, and what correspondence with it is, has been stated already. The Grand Man consists in heaven in its entirety, which in general is a likeness and image of the Lord. Correspondence is a correspondence of the Lord's Divine with the celestial and spiritual things of heaven, and of those celestial and spiritual things of heaven with natural things in the world, primarily those in man. Thus there exists, by means of heaven or the Grand Man, a correspondence of the Lord's Divine with man and every individual part of him, so much so that man comes into being from that correspondence and is all the time coming into being, that is, is kept in being, from it.
