3210. 'And Isaac brought her into the tent of Sarah his mother' means the sanctuary of truth within the Divine Human. This is clear from the meaning of 'a tent' as that which is holy, dealt with in 414, 1102, 2145, 2152, 2576, and so the sanctuary; and from meaning of 'Sarah his mother' as Divine truth, dealt with in 1468, 1901, 2063, 2065, 2904, from which the Divine Human was born, the Rational of which is represented by 'the son Isaac'. From this it is evident that 'Isaac brought her into the tent of Sarah his mother' means that rational Good guided Truth represented by Rebekah into the sanctuary of truth. What the sanctuary of truth is becomes clear from what has been stated above in 3194 about the Lord's Divine Human - that Good and Truth belong essentially to the Divine itself, but that the Lord's Divine Human came into existence from Divine Good and was born (as to the Divine itself, that is) from Divine Truth; or what amounts to the same, that the Lord's Essential Being (Esse) was Divine Good, but the Manifestation (Existere) of Him was Divine Truth. From this came Divine Rational Good to which He joined Divine Truth from the Human.

[2] It is impossible to say anything more about this very deep arcanum than this: Divine Good and Truth themselves within the Lord's Divine Human to which Truth from the Human was joined are what were meant by the Sanctuary or Holy of Holies in the Tabernacle and in the Temple. The nature of that Good and Truth was represented by the objects within the Sanctuary, such as the golden altar, the table with the loaves of the presence, and the lampstand; and further within, by the Mercy Seat and the Ark; and within it, inmostly, by the Testimony which was the Law delivered from Sinai. This was the Holy of Holies itself or Sanctuary of Truth.

1624. The form of one of the large rainbows was shown to me, so that from it I could get to know what their smallest forms were like. It was a pure white light with a kind of border, in the middle of which was a dark object as if made of earth. This was surrounded by an extremely luminous halo, itself variegated and divided up by another luminescence that had yellow dots like tiny stars. Additional variegations were produced by flowers of different colours entering the luminous area. The colours of these flowers emanated not from a white light but from a flame-like one. All of these appearances were representative of celestial and spiritual things. All the colours that are seen in the next life represent that which is celestial or spiritual. The colours emanating from the flame-like light represent things that belong to love and the affection for good, whereas colours emanating from the white light represent those that belong to faith and the affection for truth. These are the sources of all colours in the next life, and they are therefore so resplendent that the colours of this world cannot compare with them. Colours also exist there which are never seen in this world.
