This necessity for keeping the balance supplies motive for a great deal that is done by spirits in the lower strata of life in the Beyond. It is not, strictly speaking, mental balance, but organic, affecting the whole being. A spirit possessed of any conscious individuality whatever must generate a certain interior force to maintain it. This keeps his body in a state of equilibrium between the inner and outer pressure, and the body of a spirit is naturally as valuable to him as ours is to us. It protects him against currents of thought and emotion that are not adapted to his needs, and when evenly balanced he is able to put forth effective will-power along the plane of his development and below. Any one who has not learned what soul-action is will have it to learn soon after the exchange of worlds. No other form of activity is possible there. No spirit strikes another with his hand, nor presents him with a visible token of wealth, yet battles are fought and presents given. As a suggestion: when you say to your friend, "Good-bye and good-luck to you," you are making him a spiritual present, although you may not be aware of it. Whenever you launch a curse, if only in thought, you strike a blow, against which conscious rectitude is an actual armor, and the only one. The very slightest impulse of ill-will directed toward any one is an action of the soul that may do real harm, and certainly makes a record. These statements will commend themselves as true to most of my readers, many of whom, however, would not be able to explain why they are so sure of what they have learned from no teacher, and cannot recall from the pages of experience. Let me suggest. From six to nine hours' sleep is an essential part of our daily lives. We suppose ourselves to actually sleep, not only in body but in mind and soul as well. Perhaps some who have very little mind and even less spirit, do sleep when their body sleeps, but there are very large numbers of people who, the moment the brain becomes quiescent, enter at once on the most active part of their daily existence. This is especially true of such as during their waking hours have attained some knowledge of spiritual values, and have taken their stand on this or that platform of principles, religious, moral, or even political, and who would be ready to contend in argument, or even, if necessary, take up arms, in defense of their positions; in other words, who have a conscious location in some field of thought or fortress of belief. The extent to which we influence others, or are influenced by them, during our sleeping hours, very few realize, because unable to recall, when waking, the experiences of the night just passed; but be sure that no reform can ever make much progress until the agitation for it becomes sufficiently powerful to link the day to the night, and engage the activities of partially freed spirits while their bodily consciousness is lost in slumber.
