THEORY OF KARMA ( ACTION )

Karma means not only action, but also the result of an action. The consequence of an action is really not a separate thing. It is a part of the action, and cannot be divided from it. Breathing, thinking, talking, seeing, hearing, eating, etc., are Karmas. (Immannuel Kant )
Any deed, any thought that causes an effect, is called a Karma. The Law of Karma means the law of causation. Wherever there is a cause, there an effect must be produced. A seed is a cause for the tree which is the effect. The tree produces seeds and becomes the cause for the seeds.( Upnishads )-Quoted by SwamiShiwanand.
The ever changing physical, biological, psychological, ethical and spiritual components and our individual and group reactions according to our choices being empowered to be free , are the causes of our pleasure, pain and suffering. Our existence is complex combination of aggregates of all this flux-result . There is no 'One Thing' that determines anything but it is always the interconnected and interdependent flux of 'Many Things.' All this that we call Existence is in dynamic form ;action , reaction ,interaction , resulting again in action and this chain of actions goes on in multifarious/heterogeneous ways . ONE goes to two and then four then sixteen and so on and so forth . As twenty six letters form the dictionary and it is well said and correctly -this whole creation is the manifestation of ATMA /OUM / ONE SINGLE UNIVERSAL SOUL .
In this way we are left in a world where we are free to make choices of actions within limits caused by necessary forces of circumstances said above . we can not change the biological ,geographical and cultural backwe can do all this by changing our ethical grounds wherein we are born and raised but we can easily or sometime struggling and striving we can change our responses to these factors and stimuli and thus can create a new trend in our lives or improve and change that what we call fate to a great degree . we can change our ethical ,moral and mental attitude and can turn the direction of our present action and living condition as Lord Bauddha , Socrates .Gandhi and many more did .We have a fate ,no doubt , but we can change it ,improve it ,remake it and can write otherwise ,good or bad .(but within limit and limit is not known so far )
You are what your deep driving desire is;As your deep driving desire is, so is your will;As your will is so is your deed;As your deed is so is your destiny.(Upanishad)

As long as we are persistent in our pursuit of our deepest destiny, we will continue to grow. We cannot choose the day or time when we will fully bloom. It happens in its own time. (Denis Waitley )
This is the excellent foppery of the world, that when we are sick in fortune (often the surfeits of our own behaviour) we make guilty of our disasters the sun, the moon, and stars: as if we were villains on necessity; fools by heavenly compulsion; knaves, thieves, and treacherous by spherical predominance; drunkards, liars, and adulterers by an enforced obedience of planetary influence; and all that we are evil in, by a divine thrusting on. An admirable evasion of whoremaster man, to lay his goatish disposition on the charge of a star!(W.SHAKESPEARE, King Lear )
