Something as simple as allowing is a concept many of us have trouble with because it seems like we aren't 'doing' anything.
Trying is the energy of searching but never finding. It is the realm of the conscious mind and contributes to stress, unhappiness, even ill health. As long as you focus your efforts on trying, you prevent yourself from having.
Allowing, on the other hand, is the realm of Source mind, our greater capacity. It is the energy of having, of achieving, of succeeding. It is not a passive state--but actually quite active. When you are in allowing, you are open to receive inspiration and inspired action.
Very different attitudes, different outcomes and different energies used.
Plus allowing is just more fun once you get the hang of it!
