If you observe matter on a quantum level, all matter displays both wavelike and particle-like properties. Quantum mechanics suggests that the behavior of matter and energy is inherently probabilistic and that the effect of the observer on the physical system being observed must be understood as being part of that system. 

So energy is in constant flux or in other terms, it's continually moving and changing, which can be seen when you look at it on teeny, teeny tiny levels. Basically, what this definition is saying is that if you observe an item, it becomes possible for you to be a part of that item as one unit. You can influence the energy of the unit or group on how it will behave. 

Maybe oversimplified, energy is like a puppy full of potential who is eager to be told how to act and for you to take control, and the more work you put in, the better results come out of it. 

The same goes for a piece of jewelry that, in our case, can work as an anchor. The more often we fill it with positive intentions and goals, the better the outcome. With consistent practice and positive thought patterns in combination with meditation, you can hone in on your goals much more efficiently by the positive energy (that you infused on subatomic levels) emitting from your jewelry.
