How does karma know who to target and what to do?

The precision of the karmic response to the launching of energy, by the conscious acts of an individual, follows from the energy created being stored on record in the vast repository of all knowledge. The akashic record maintains a recorded sequence of all that happens and the energetic signature of all who participated, and the details of the interchange are included as well. In this way, everything that happens, good or bad, is defined and described in an accurate and exact representation as an energetic signature that is very much like a biographical sketch describing the main characters, the course of events, what transpired, and what were the consequences. This is a dynamic, ever-changing body of information as new experiences are added constantly and old ones are extended through the looping of time and the rendering of the karmic backlash to further alter the trail of events as the energy circles back around to the original actions, and who was responsible, and then the energy will impinge and this will have consequences that further modify the ongoing record and will either be improving things or worsening them for the most part, thereby creating new karma with consequences. This re-echoing and re-echoing is very much a consistent feature of karma and is responsible for much negativity and unhappiness. This is very evident in many people's lives where they seem to be in a rut, repeating the same mistakes again and again, or have the same seeming bad luck befall them again and again and again. It is partly learned behavior and habit, but always a significant part of what takes place is the energy of karma impinging on the individual in their circle to carry out their role in recreating a prior karmic event with a new variation or version at times, but always following a script previously written and launched energetically. It is very much like the script of a play that will be enacted again and again, much as people come together to rehearse the same scene again and again until they get it right. In this case they are rehearsing the re-living of a prior circumstance to see if they can change what happens sufficiently to bring about a final resolution that will heal all that took place and let all the parties off-the-hook, so to speak, so they can stand down and return to other matters, and no longer have to repeat the same series of mistakes or exaggerated responses to something, and thereby worsen things.
