The Principle of Cause and Effect states that:

 "Every Cause has its Effect; every Effect has its Cause;

  everything happens according to Law; Chance is but a

  name for Law not recognized; there are many planes of

  causation, but nothing escapes the Law."

So while there is a lot to unpack, one of the more interesting aspects of this principle is the idea that chance or randomness does not occur in our universe. This is interesting because if true, it means that nothing, and I mean NOTHING, ever happens randomly, instead every moment and every event that has ever occurred has happened for a reason.  

And if everything happens for a reason this then implies that we are then bound to fate. And if we are bound to fate this means that everything that has happened in your life thus far, was destined to happen, that your life has been predetermined...
