9597. 'With cherubs' means the Lord's watchfulness, guarding it from the approach of the hells and the harm they can do. This is clear from the meaning of 'cherubs' as watchfulness and providence, preventing any approach to the Lord except through good and protecting from harm the good from the Lord which exists in heaven and with man, dealt with in 9509, consequently guarding heaven from the approach of the hells and the harm they can do.

422. The world of spirits is an intermediate place between heaven and hell and also an intermediate state of the man after death. It has been shown to me not only that it is an intermediate place, having the hells below it and the heavens above it, but also that it is in an intermediate state, since so long as man is in it he is not yet either in heaven or in hell. The state of heaven in man is the conjunction of good and truth in him; and the state of hell is the conjunction of evil and falsity in him. Whenever good in a man-spirit is conjoined to truth he comes into heaven, because that conjunction, as just said, is heaven in him; but whenever evil in a man-spirit is conjoined with falsity he comes into hell, because that conjunction is hell in him. That conjunction is effected in the world of spirits, man then being in an intermediate state. It is the same thing whether you say the conjunction of the understanding and the will, or the conjunction of good and truth.
