9653. 'And for the two legs of the dwelling-place towards the sea' means a joining to heaven where good dwells in obscurity. This is clear from the meaning of 'two' as a joining together, as above in 9645; from the meaning of 'the legs' as the borders where good dwindles into obscurity, dealt with in 7859; from the meaning of 'the dwelling-place' as heaven, dealt with in 9594; and from the meaning of the west or 'the sea' as a state of good in obscurity, dealt with in 3708, 8615. This state is meant by 'the west' because the Lord in respect of the good of love is meant by 'the sun', 3636, 3643, 4060, 4321 (end), 7078, 7083, 7171, 8644, 8812. Therefore 'the east' where the sun rises means the good of love from the Lord where the perception of it is clear, and 'the west' where the sun goes down means good from Him where the perception of it is obscure. And since a person's and an angel's perception is clear when they have been raised towards more internal parts or into the light of heaven, and their perception is obscure when they remain in more external parts, 9648, thus when they remain in the light of the world, the west is also called the sea. For 'the sea' means factual knowledge in general, 28, 2850, and factual knowledge resides in the external or natural man, where good lies in obscurity. All factual knowledge, since it belongs to the natural man, dwells in the light of the world.

7078. It should be recognized that spirits belonging to other planets do not appear within the sphere where spirits belonging to our planet are but outside, some quite a distance away, others less far, and also in different directions. One reason for this is that the spirits belonging to one planet do not have the same disposition and life as spirits belonging to another; and another reason is that they constitute different provinces in the Grand Man. Unlikeness in their states of life is responsible for this appearance of separateness; but in the inmost heaven they do not appear separated from one another. The spirits belonging to Mercury however do not appear in any particular direction or at any particular distance but are seen at one time in a forward position, at another over on the left, or at another slightly behind the back. The reason for this is that they are allowed to wander everywhere to acquire items of knowledge and thereby enrich their memory. Their planet is presented to spirits as being behind the back, in the same way as the sun of the world is when they think about it; for nothing at all of it is visible. The reason why it is presented behind the back is that to those who are in the next life the sun of the world is in complete obscurity and is itself thick darkness, whereas the sun of heaven, which is the Lord, appears in front, before the right eye, because it is the source of all the light they have. For the right eye corresponds to the ability to see with the understanding not only in the measure that the understanding is enlightened by truth but also in the measure that it is [affected] by good, 4410, so that the Lord views a person [with the eye of] good, and enlightens him by means of good.
