238. The Word in the letter is like a casket, where precious stones, pearls, and diadems lie in order. The thoughts of a man's mind, who regards the Word as holy, and who reads it for the sake of the uses of life, may be compared to one holding such a casket in his hand, and throwing it toward heaven; and the casket opening in its ascent, the precious things in it are disclosed to the angels, who are deeply delighted in seeing and examining them. This delight of the angels is communicated to the man, and effects an affiliation and a sharing of perceptions. For the sake of this affiliation with angels, and at the same time conjunction with the Lord, the Holy Supper was instituted, the bread of which in heaven becomes Divine good, and the wine Divine truth, each from the Lord. Such correspondence exists by creation, to the end that the angelic heaven may make one with the church on earth, and in general the spiritual world may make one with the natural world, and the Lord may conjoin Himself with both at once.
