“His overriding life necessity was not love, it was his profession…He had come to medicine not by coincidence or calculation but by a deep inner desire. Insofar as it is possible to divide people into categories, the surest criterion is the deep-seated desires that orient them to one or another lifelong activity. Every Frenchman is different. But all the actors the world over are similar.”

“Take for instance a man driven to incessant work by a sense of deep insecurity and loneliness; or another one driven by ambition, or greed for money. In all these cases the person is the slave of a passion, and his activity is in reality a "passivity" because he is driven; he is the sufferer, not the "actor." On the other hand a man sitting quiet and contemplating, with no purpose or aim except that of experiencing himself and his oneness with the world, is considered to be "passive", because he is not "doing" anything. In reality, this attitude of concentrated meditation is the highest activity there is, an activity of the soul, which is possible only under the condition of inner freedom and independence.”

“What destroys a man more quickly than to work, think and feel without inner necessity, without any deep personal desire, without pleasure - as a mere automaton of duty?”

“A man's calling is written on his true heart, and he discovers it when he enters the frontier of his deep desires.”

“Look deep into your heart, Gentle Reader. Deep, deep, deep; past your desire for true love, for inexhaustible riches or uncontested sexual championship, for the ability to fight crime and restore peace to a weary world. Underneath all this, if you are a true, red-blooded American, you'll find the throbbing desire to be famous.”

“Why do people all over the world, and at all times, want marvels that defy all verifiable facts? And are the marvels brought into being by their desire or is their desire an assurance rising from some deep knowledge, not to be directly experienced and questioned, that the marvelous is indeed an aspect of the real?”
