Cosmic Law states that Power (As is our Life-Force, Energies and Abundance) is there for all to use. If your power is unusedlying there, so to speakthen others may use itwithout your knowledge! Unless you Claim Your Power and qualify it, by stating as above that it is yours and yours alone to use, etc
The use of your Power without your knowledge is allowed and there are lots of beings out there that work very hard at keeping you in a state of confusion, so that you won't know that they have and are using your Power! This is one of the important reasons for you to Claim Your Power.
