In 1687 Sir Isaac Newton published a revelation for the science community. It was called Philosophiae Naturalis Principia Mathematica, and contained three simple laws of motion that are still a cornerstone for the science of physics today.
These laws describe the relationship between the forces acting on a body and the change in its motion due to those forces. They also describe the relationship of forces and bodies on a more metaphysical level. Namely how external and internal energy can change a person in very profound ways. They are yet another sign that the physical and metaphysical worlds are more connected that many may think.
His first law states that "objects in motion stay in motion unless an external force is applied to it". In other words a hockey puck will continue to slide on ice until it hits something, or the force of friction slows it down, and even stops it. On the more philosophical level it also means that unless some force acts to change your life, your life will go on, just as it has, without change, until it eventually comes to an end. Only by exerting some type of force to your life can you hope to change.
That force can take the form of a catastrophic event that rocks you so profoundly that you are forced to question who and where you are in life. It can also take the form of a new romantic interest who sends you reeling in the same way. The problem with outside forces though, is that you have little control over where you end up. Much like the way a hockey puck has little control over where it goes after being hit by a stick.
Fortunately you are not an inanimate object. You have freewill and can create the change yourself by actively seeking a powerful force of your own choosing if you want. You can turn to drugs or alcohol if you want. But again those are outside forces that you don't always have control over. More often than not they end up being a negative influence, rather than the positive forces you thought they were when you first tried them.
There are other forces you can bring into play that you can manage and that will lead to positive change. Practices like meditation, yoga, and even religion can be even more powerful forces of change because they come from within, and because you can guide them with practice. Which is why I added a corollary to Sir Isaac Newton's first law for the metaphysical world:
