Perfection to me is first most an ideal. To me, it could be summarized as a most difficult path along the way to union with God. Primarily through prayer, silence, and meditation one can indeed seek perfection in other words be in direct communion with God.
It is not a popular path to embark on; yet indeed, it is one with extraordinary revelation. When one is "climbing" this path the most extraordinary observation is always the significant peacefulness and contentment of agape love. Thus, perfection to me is a most difficult "climb" to peacefulness and agape love. Perhaps the most invaluable gift from God.
