Does the Soul need Sleep?

As per Ralph Waldo Trine:

“Sleep, then, is for the resting and the rebuilding of the body. The soul needs no rest, and while the body is at rest in sleep the soul life is active the same as when the body is in activity. There are some, having a deep insight into the soul’s activities, who say that we travel when we sleep. Some are able to recall and bring over into the conscious, waking life the scenes visited, the information gained, and the events that have transpired. Most people are not able to do this and so much that might otherwise be gained is lost. They say, however, that it is in our power, in proportion as we understand the laws, to go where we will, and to bring over into the conscious, waking life all the experiences thus gained. Be this, however, as it may, it certainly is true that while sleeping we have the power, in a perfectly normal and natural way, to get much of value by way of light, instruction, and growth that the majority of people now miss.

If the soul life, that which relates us to Infinite Spirit, is always active, even while the body is at rest, why may not the mind so direct conditions as one falls asleep, that while the body is at rest, it may continually receive illumination from the soul and bring what it thus receives over into the conscious, waking life? This, indeed, can be done, and is done by some to great advantage; and many times the highest inspirations from the soul come in this way, as would seem most natural, since at this time all communications from the outer, material world no longer enter. By charging the mind on going to sleep as to a particular time for waking, it is possible as many of us know, to wake on the very minute. The mind acting intently along a particular line will continue so to act until some other object of thought carries it along another line. And since in sleep only the body is in quiet while the mind and soul are active, then the mind on being given a certain direction when one drops off to sleep, will take up the line along which it is directed, and can be made, in time, to bring over into consciousness the results of its activities. Some will be able very soon to get results of this kind; for some it will take longer. Quiet and continued effort will increase the faculty.”
