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.
The sage wears clothes of coarse cloth but carries jewels in his bosom; He knows himself but does not display himself; He loves himself but does not hold himself in high esteem.
Pride attaches undue importance to the superiority of one's status in the eyes of others; and shame is fear of humiliation at one's inferior status in the estimation of others. When one sets one's heart on being highly esteemed, and achieves such rating, then he or she is automatically involved in fear of losing status.
Better stop short than fill to the brim. Oversharpen the blade, and the edge will soon blunt. Amass a store of gold and jade, and no one can protect it.
