An authority says on this phase of the question: "There is no doubt whatever that, just as what is happening now is the result of causes set in motion in the past, so what will happen in the future will be the result of causes already in operation. Even on this plane of life we can calculate that if certain actions are performed, certain results will follow; but our reckoning is constantly liable to be disturbed by the interference of factors which we have not been able to take into account. But if we raise our consciousness to the higher planes we can see much further into the results of our actions. We can trace, for example, the effect of a casual word, not only upon the person to whom it was addressed, but through him on many others as it is passed on in widening circles, until it seems to have affected the whole country; and one glimpse of such a vision is more efficient than any number of moral precepts in impressing upon us the necessity of extreme circumspection in thought, word, and deed. Not only can we from that plane see thus fully the result of every action, but we can also see where and in what way the results of other actions apparently quite unconnected with it will interfere with and modify it. In fact, it may be said that the results of all causes at present in action are clearly visible--that the future, as it would be if no entirely new causes should arise, lies open before our gaze. "New causes of course do arise, because man's will is free; but in the case of all ordinary people the use which they make of their freedom may be calculated beforehand with considerable accuracy. The average man has so little real will that he is very much the creature of circumstances; his action in previous lives places him amid certain surroundings, and their influence upon him is so very much the most important factor in his life-story that his future course may be predicted with almost mathematical certainty. With the developed man the case is different; for him also the main events of life are arranged by his past actions, but the way in which he will allow them to affect him, the methods by which he will deal with them and perhaps triumph over them--these are all his own, and they cannot be foreseen even on the mental plane except as probabilities.
