Deuteronomy 6:5-9 Symbolism of the frontlets

⁵ And thou shalt love the Lord thy God with all thine heart, and with all thy soul, and with all thy might.
⁶ And these words, which I command thee this day, shall be in thine heart:
⁷ And thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thine house, and when thou walkest by the way, and when thou liest down, and when thou risest up.
⁸ And thou shalt bind them for a sign upon thine hand, and they shall be as frontlets between thine eyes.
⁹ And thou shalt write them upon the posts of thy house, and on thy gates.
-Deuteronomy 6:5-9 King James Version (KJV)

And shall put it upon the two posts and upon the lintel. That this signifies the truths and the goods of the natural, is evident from the signification of the "posts of a door," as being the truths of the natural; and from the signification of "the lintel," as being its goods. The posts and the lintel have this signification because by a "house" is signified man himself, or his mind, and by those things which belong to a door are signified the things which serve to introduce. That these are the truths and the goods of the natural is evident; for the natural man is instructed before the rational, and the things which the man then learns are natural things, in which are successively instilled spiritual things, which are interior. From this it is evident how the natural in respect to truths and goods serves to introduce. Moreover, the lintel and the posts have a like signification to the forehead and hands with man. Angelic ideas are of such a nature that natural things bear relation to such things as belong to man. The reason is that the spiritual world or heaven is in the form of a man, and all things of that world, that is, all spiritual things, which are truths and goods, bear relation to this form, as has been shown at the end of many chapters in treating of correspondences. And whereas in angelic ideas natural things become spiritual, so also does a house, which to the angels is the mind of man; the bedchambers and inner rooms being the interiors of the mind; and the windows, the doors, the posts, and the lintels, the exteriors of the mind, which introduce. As angelic ideas are of such a nature, they are also living; and so when the things in the natural world which are dead objects, pass into the spiritual world, they become living objects; for everything spiritual is living, because it proceeds from the Lord...
