The main conception of karma: "As a man soweth, so shall he also reap," is easy to grasp. But the application of this to daily life in detail, the method of its working and its far-reaching consequences-these are the difficulties which become more bewildering to the student as his knowledge increases. The principles on which any natural science is based are, for the most part, readily intelligible to people of fair intelligence and ordinary education; but as the student passes from principles to practice, from outline to details, he discovers that difficulties press upon him, and if he would wholly master his subject he finds himself compelled to become a specialist, and to devote long periods to the unraveling of the tangles which confront him. So is it also with this science of karma; the student cannot remain always in the domain of generalities; he must study the subdivisions of the primary law, must seek to apply it in all the circumstances of life, must learn how far it binds and how freedom becomes possible. He must learn to see in karma a universal law of nature, and learn also, as in face of nature as a whole, that conquest of and rule over her can only be gained by obedience.
