Late have I loved Thee, O Lord; and behold, Thou wast within and I without, and there I sought Thee. Thou was with me when I was not with Thee. Thou didst call, and cry, and burst my deafness. Thou didst gleam, and glow, and dispell my blindness. Thou didst touch me, and I burned for Thy peace. For Thyself Thou hast made us, and restless our hearts until in Thee they find their ease. Late have I loved Thee, Thou Beauty ever old and ever new. Thou hast burst my bonds asunder; unto Thee will I offer up an offering of praise.
True and lasting inner peace can never be found in external things. It can only be found within in. And then, once we find and nurture it with ourselves, it radiates outward.
No weapon has ever settled a moral problem. It can impose a solution but it cannot guarantee it to be a just one. You can wipe out your opponents. But if you do it unjustly you become eligible for being wiped out yourself.
