The reactions from the forces we generate naturally do us exact justice just because they _are_ reactions. We reap precisely what we sow. The reaction may sometimes seem harsh but consideration of the matter from all points of view will show that mercy as well as justice is always a factor. Let us consider the method by which nature changes recklessness into caution. A man is careless, we will say, about lighting a cigar and throwing the burning match down wherever it may happen to fall. He may go on doing that a long time with no serious result, yet all careful people know that he is a source of danger. Some time ago a newspaper told the story of such a man, who passed along the street, lighted a cigaret and carelessly flung the flaming match from him. A nurse was passing with her charge in its tiny carriage. The match fell on some of the light, airy wraps of the infant and they burst into a blaze. Before the fire could be extinguished the child was so badly burned that it died the next day. The moment such a case is stated we realize the necessity of something that will cure the man of such fatal carelessness. He is a menace to the lives and property in his vicinity. No law, however, can be invoked. He had no criminal intent but he is none the less dangerous for that, as the incident proved. We are helpless, however, to prevent his continued carelessness. But nature is not helpless. Under the law of action and reaction he must reap as he has sown. It may be in the latter part of this incarnation, or it may be in a following one, but sooner or later his carelessness will react and he will lose his physical body in pain and distress and come to know personally just what his recklessness means. In the reaction, a part only of which is on the physical plane, he gets the experience that is necessary to set him right. The folly of his course is so driven in on his consciousness that he is changed from the careless man to the careful man. In no other way could his cure be brought about. It may be said that if a misfortune comes to us as the result of our wrong thinking and acting in a past life we can now know nothing of its cause and therefore we cannot profit by the reaction. But while we do not know in the limited consciousness of the physical brain the soul does know and in the wider consciousness the lesson is registered. The principles of justice are never violated in teaching the soul its evolutionary lessons. Nothing can come to a man that he does not merit and that which often looks like a misfortune is only the beneficent working of the law seen from an angle that makes it illusory. But, it may be objected, how does theosophy see "beneficent working of the law" in the burning of a theater where a score of people lose their lives, including several children? How can theosophy explain that?
