Karma lives with us, Karma is part of our lives from the very moment of our birth to the moment of our death. Every time that we do something and every time that we stop doing something, that generates Karma, and you cannot avoid it in any way.
Of course, not all the Karma that we generate is the same, there is a kind of Karma that ties us or chains us to this life, and another kind that liberates us of the reincarnation cycle. The Karma that chains us, known as Vishayakarma, has as fruits misery and lack of interior peace, while the Karma generated by good actions or disinterested actions, know as the Sreyokarma allow us to reach prosperity and happiness of the soul, that is much more than reaching simple external happiness.
Everytime that we face an activity with the desire of obtaining a certain result, this throws us into the arms of desire, greed and ego. While only the pure actions that we do for love without taking into account the possible consequences of them, are the kind of actions that drive us, little by little, toward illumination and liberation. Those whose nature allows them to carry out these kinds of unselfish activities, little by little, realize that Spirit provides them with all that they need and inner peace. Another form of achieving inner peace is through meditation.
Perhaps you might ask yourself why? Why is meditation so necessary? Because humans always act in two dimensions, the external dimension governed by the physical senses, and the internal dimension governed by the inner knowing and the mind. The internal conscience cannot move for itself, but instead, needs intelligence and the mind, for they are the oxen that pulls the carriage. These oxen are anxious to begin to walk, but to take us to the correct destination they should be educated, they should study which is the route that takes us to the place to which we want to arrive at the internal conscience. And these are the roads of Truth, Rightness, Peace and Love.
