“He must fall either by the hand of his enemies, or by himself; for he is his own worst enemy.” – Marcus Tullius Cicero, Familiar Short Sayings of Great Men, 6th ed., comp. by Samuel Arthur Bent. Boston: Ticknor and Co., 1887
A troubled heart is a human weapon of mass destruction, for it is from this one device that all evils experienced by man on earth spring. Contrary to popular opinion and longstanding human belief, a troubled heart, in the sense of a heart not at rest in the supremacy of love, the inviolability of truth and the perdurable victory of life – is never justified. No set of appalling circumstances, no injustice, no tragedy warrants the relinquishment of this trust.
An tranquil heart, by contrast, is what allows man to live creatively. When your heart is untroubled, you are protected from your enemies by radiance. Once they are neutralized in this manner, the only remaining adversary is you. Conquer yourself by yielding wholeheartedly to the injunction “Let not your heart be troubled” and you will overcome the world.
This, unfortunately, is not an area of function in which you can “fake it ’til you make it.” Your heart is either a sea of glass, like unto crystal or its waters are disturbed. This is not a passive state; it is a state of being that is simultaneously unmoved by the cares of this world and carefully tuned to the pulsations of wisdom which are always at hand.
