ever present energy

energy is a word that cant be defined by any one definition. energy is however every present, cannot be created or lost, only transformed. Some people claim that spirts from the other word are present in ours and can be seen or at the very least "felt" through increased energy patches. these experiences could be results of the mind playing tricks on the body or maybe there are increased energy areas. the only problem is that these cants be proven and thus there will always be skeptics.
