9817. 'And you shall speak to all the wise at heart' means an influx from the Lord through the Word into all who are governed by the good of love. This is clear from the meaning of 'speaking' as influx, dealt with in 2951, 5481, 5743, 5797, 7270; and from the meaning of 'the wise at heart' as those who are governed by the good of love, dealt with below. The reason why influx from the Lord through the Word is meant is that for members of the Church the main channel by which the Lord flows in is the Word. This is so because the nature of the Word is such that all things without exception there correspond to the Divine spiritual and Divine celestial realities that exist in the heavens; and as a result of this a person shares affections and thoughts with angels, in so complete a manner that he and they are seemingly one. So it is that the world has been joined to heaven through the Word, but only among those who are governed by the good of faith and love. From all this it becomes clear that for members of the Church the Lord flows in through the Word; for the Lord is the all in the heavens, since what is Divine and emanates from the Lord, and is received by angels, composes heaven.

[2] The reason why 'the wise at heart' means those who are governed by the good of love is that the presence of wisdom in a person is attributable to the life of heaven in him, also that 'heart' means the good of love. In the Word 'spirit' and 'heart' are expressions that have regard to the life of heaven present with a person, 'spirit' being used to mean that life in the understanding part of the person's mind and 'heart' that life in the will part. To the understanding part belongs truth, but to the will part belongs good; the former has to do with faith, but the latter with love. For the understanding receives truths that constitute faith, and the will forms of good that are aspects of love. From this it is evident that by 'the wise at heart' those governed by the good of love received from the Lord are meant. The good of love is celestial good, through which spiritual good comes into being; and spiritual good is that which covers celestial good, like garments the body. And since Aaron's garments represented the Lord's spiritual kingdom lying adjacent to His celestial kingdom, and the former comes into being through the latter, the present verse goes on to say that 'the wise at heart', that is, those governed by the good of love received from the Lord, should make the garments for Aaron and his sons. As regards 'heart', that it means the good of love or celestial good, see 3635, 3880, 3883-3896, 9050; and that it therefore means the will, 2930, 3888, 7542, 8910, 9113, 9300, 9495.

3888. Those two kingdoms manifest themselves in man through the two kingdoms which exist within him - the kingdom of the will and the kingdom of the understanding which constitute man's mind, indeed man himself. It is the will to which the beating of the heart corresponds, and the understanding to which the breathing of the lungs corresponds. Those two kingdoms also manifest themselves in man's body, where again there are two kingdoms - that of the heart and that of the lungs. Anyone who knows this arcanum is also able to know about the influx of the will into the understanding and of the understanding into the will and consequently to know about the influx of the good of love into the truth of faith, and vice versa, and so about the regeneration of man. But people who are restricted solely to bodily ideas, that is, people who have evil as the object of their will and falsity the object of their understanding cannot grasp these matters, for they cannot think about spiritual and celestial things except with the senses and the body. Consequently they cannot think of those things except from a thick darkness concerning the things that constitute heavenly light, which is the truth of faith, and from a coldness concerning the things that constitute heavenly flame, which is the good of love. Those two - the thick darkness and the coldness - so blot out celestial and spiritual things that they do not seem to those people to be anything.
