There are events in our life that are inexplicable to us, good or bad events that occur again and again throughout our existence, Coincidence?.
Karma is the result of our past actions, not just the past of our life, but also of other lives. It is an Education Act, is neither reward nor punishment, is a sign that something we have not learned.
By the time we understand the cause of each of the events of our lives, then we have the ability to transmute (change) our karma and therefore, change our destiny.
Concept of Karma: The law of psychospiritual growth involving an equal and opposite way to each action. Karma is a process that ensures the evolution of consciousness.
The above definition may sound familiar, it might be an equivalent to Newton's law in the field of physics. Physicists like Newton and Einstein had a wide knowledge of physics and the relationship of the universe with man, but it seems that so far we have ignored these concepts.
Knowledge of Karma helps us understand the facts "inexplicable" that happen throughout our lives.
Karma is a Universal Law that teaches us that for every action we take will be a logical reaction. All our actions have a consequence.
We could use the Karma as a sign, if something goes wrong in our lives, simply make a factual analysis to conclude where we are failing.
Karma is not a matter of reward or punishment, nor is there a target letter, or that our success or failure was due to "our good fortune." Our life is our responsibility, and karma teaches us just that, we are ourselves responsible for our actions and not blame circumstances, fate or our family for our failure. Given this knowledge, we go right to arming our lives with full awareness of what will be the end result in every action.
First and Second Laws of Motion are also paradigms hidden personal and spiritual growth.
Every body remains in a state of rest or uniform motion in a straight line unless a force acts carried externally. (Translation: If you keep doing what you've always done, you'll keep getting what you've always gotten. Someone said to imagine another way of doing things is a good definition of "insanity".)
The level of change of momentum is proportional to the force, and takes place in the same direction of force. (Translation: "God helps those who help themselves").
Here I quote some passages from the New Testament where there any references about karma:
... do not feel deceived: God is not mocked: for whatever a man sows, that will be your harvest.
... for he who sows in the flesh of the flesh reap corruption of it, but he who sows to the Spirit, the Spirit reap eternal life.
.... and not grow weary in well doing: for in due time reap if we faint not.
Gal, Cap. 6:7-9
Karma goes beyond any religion, is a Universal Law that comes from the Hindu and Buddhist philosophy. These are actions and consequences and has nothing to do with religion that professes. It is a law that is always present.
