In respect to the law according to which they come to be worked out in their turn, the Karma-seeds, white and black, are of three classes—Sanchit, Prārabdha and Kriyamān or Agāmi. Sanchit means stored-up. Prārabdha means Karma the reaction of which has begun or that which is working now. Kriyaman means Karma-seeds originating out of the Prārabdha Karma now being worked out, but which will form the seeds of future (Agami) actions. Sanchit Karma includes the seeds of all the actions of past existences stored up as impressions on the mind. Out of this storehouse of Karma-seeds that, white or black, which is the most powerful asserts itself to be worked out first, drawing to itself, by the law of affinity. Karma-seeds of minor power, but of a nature similar to its own. This most powerful Karma-seed, lumped up with small Karma-seeds of similar character, forms the Prārabdha Karma, Karma which is in the process of being worked out. And in its process of working the fresh thought-impressions which the mind is registering are called Kriyamān (Karma being born), also called Agāmi (future) Karma, Karma seeds which, after being deposited in the storehouse, will come to be worked out in their turn in future, either as main or minor Prārabdha, according to their potency. This is the law of working of human Karma, the inexorable law which shapes our life and destiny, which fills existence with joy or sorrow. Karma is unending unless we learn the mysterious law which works it and grasp the still more mysterious Law behind that Karmic law and by its practice destroy its roots and prevent its present and future actions within us. I will speak of this Law and of its ways of practice later on. We often see a man, who has lived a good, pure and harmonious life, suddenly, through circumstances or bad associations, changed into a bad man. He becomes worse in habits and conduct and dies in that degraded mental state. Similarly we find some one very bad up to a certain period of life; he suddenly turns good and, before death, develops into an angelic character. This law of Karma is behind this change of character. Good Prārabdha influences one into good life and actions while it is working. But if some black Karma-seed is the most powerful of all Karma-seeds in the mind's storehouse, after the good Prārabdha has been worked out, it asserts itself to be worked out next and, lumped up with the minor seeds, forms his Prārabdha which changes the whole complexion of his character and conduct. The case of a bad man becoming good is subject to the same law; a white Prārabdha, owing to its predominant power, succeeds a bad one. The liability of alternate succession of bad and good Karma producing the actions of human beings is expressed in the metaphoric saying that the action of Karma in man is like a revolving wheel.
