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.

3635. In the human body there are two organs which are the mainsprings of its entire movement, and also of every action and external or purely physical sensation - the heart and the lungs. These two so correspond to the Grand Man or Lord's heaven that celestial angels there constitute one kingdom, and spiritual angels the other, for the Lord's kingdom is celestial and spiritual. The celestial kingdom consists of those who are governed by love to the Lord, the spiritual kingdom of those who are governed by charity towards the neighbour, 2088, 2669, 2715, 2718, 3235, 3246. The heart and its kingdom in man corresponds to celestial angels, the lungs and their kingdom to spiritual ones. Also the angels flow into things belonging to the heart and lungs, so much so that these things receive their being and are kept in being by means of that influx from them. But the correspondence of heart and lungs with the Grand Man will in the Lord's Divine mercy be presented as a separate subject.
