It is common in the Bible for people to "rise up," and it would be easy to pass over the phrase as simply describing a physical action. But in fact it represents an elevation in spiritual state, moving to a more internal frame of mind closer to the Lord. Often it has to do with understanding a new or important idea; we "rise up" to a state of greater perception and enlightenment. Obviously context is crucial to the exact meaning of the phrase in a given passage -- it matters greatly who it is that is rising up, and why.

511. In this second state the separation of evil spirits from good spirits takes place. For in the first state they are together, since while a spirit is in his exteriors he is as he was in the world, thus the evil with the good and the good with the evil; but it is otherwise when he has been brought into his interiors and left to his own nature or will. The separation of evil spirits from good spirits is effected by various means; in general by their being taken about to those societies with which in their first state they had communication by means of their good thoughts and affections, thus to those societies that they had induced to believe by outward appearances that they were not evil. Usually they are led about through a wide circle, and everywhere what they really are is made manifest to good spirits. At the sight of them the good spirits turn away; and at the same time the evil spirits who are being led about turn their faces away from the good towards that quarter where their infernal society is, into which they are about to come. Other methods of separation, which are many, will not now be mentioned.
