Peacefulness is an inner sense of calm - it comes from becoming still - in order to reflect and meditate on our inner wisdom and receive answers. A peaceful heart is one that is free from worry and rouble. It's becoming quiet so we can look at things quietly so we can more clearly understand them and thus come up with creative solutions. It is learning to live in the present. Freedom from desire leads to inner peace.
LaoziThe greatest teacher has nothing to say. He simply gives himself in service, and never worries.
LaoziBeing deeply loved by someone gives you strength, while loving someone deeply gives you courage.
LaoziThe wise stand out because they see themselves as part of the Whole. They shine because they don't want to impress. They achieve great things because they don't look for recognition. Their wisdom is contained in what they are, not their opinions. They refuse to argue, so no-one argues with them.
