The Omega Principle
If Creation has happened and this universe has existed in 84 different versions, then it's incredibly likely that you have also existed at least 84 different times. While there is no trace of 63 of your previous lives some 21 of your previous lives and existences have some trace in your current life and existence.
Karma is not always a straightforward process of cause and effect when it comes to choice and consequences. Some of the choices someone makes when they are 35 years old may arise out of consequences they experienced when they were six years old. Let's say you kicked a ball which broke a window when you were nine years old, and at the age of 29 you find yourself suddenly being attacked in the street. Insight from your past experience might cause you to kick your assailant hard and get away. This is an example of a connection between a consequence and a choice across twenty years of life.
Similarly you might find yourself in a current situation in life which happens again and again but when you are at different ages and this consequence or situation you face might be the result of choices you made in a previous life, of which you have no conscious memory.
Our connections to other people
Similarly some people come into your life for a reason and often this reason might be a consequence of a past choice you have made, either in your current life or a previous life. Sometimes your connection with that person will result in an issue or a conflict. Sometimes your connection to another person resolves a struggle or conflict you have been experiencing.
This can be significant when you are seeking love. You may be seeking love from people you meet in your current life, but what you might find is that you can connect to some people and the connection feels as if you have known them throughout your whole life. Sometimes you connect to someone, but they don't feel any connection to you. Or vice versa, someone feels a connection to you, but you don't feel it. Have you ever felt that the reason you connect to others is a sense of unfinished business or something incomplete?
The Omega Principle was developed by Stella Baker around the end of the last century and is a principle about simplicity and complexity which is all somehow related to karma.
