"A Course in Miracles" talks about the holy instant. It is that moment right after someone says something, or something happens, or we have a thought. Will we react or respond, and if so, how? Does the thought scare us, and will we decide to run with (thereby creating whatever it is), or do we just allow it to flow right on through?
Our "power" for March is Strength. Our perception of strength may be pushing, shoving, overpowering force. But strength is also expressed in practicing restraint--in taking that holy instant and deciding what is true for us and what is not, rather than just reacting from ego, fear, resentment--like we always have.
