Text of the meditation
All things, whether visible or invisible, are subservient to, and fall within the scope of, the infinite and eternal law of causation. Perfect justice upholds the universe; perfect justice regulates human life and conduct. All the varying conditions of life, as they exist in the world today, are the results of this law reacting on human conduct.
A person can, and does, choose what causes they will set in operation, but they cannot change the nature of effects; they can decide what thoughts they will think and what deeds they will do, but they have no power over the results of those thoughts and deeds; these are regulated by the overruling law.
A person has all power to act, but their power ends with the act committed. The result of the act cannot be altered, annulled or escaped; it is irrevocable. Evil thoughts and deeds produce conditions of suffering; good thoughts and deeds determine conditions of blessedness.
