Calmness is one of the beautiful qualities of the spiritual person. It includes calmness of the heart, nerves, thought, senses, behaviour and body. A quiet person’s heart never becomes troubled for any reason. He does not lose his calm no matter how the problems are caused. As the prophet David says “Though an army should encamp against me, my heart shall not fear; though war should rise against me, in this I will be confident” (Ps. 27:3). It is this type of calmness that comes from faith.
If one loses ones inner peace, everything will look disturbed in ones’ eyes, and what is simple will seem complicated. This complication is not from the outside but from the inside. When the heart is calm the nerves will also be calm. In this case one would not lose temper but, instead, quietly solve the problem.
