"To develop a broader vision we must be willing to forsake, to kill, our narrower vision. In the short run it is more comfortable not to do this - to stay where we are, to keep using the same microcosmic map, to avoid suffering the death of cherished notions. The road of spiritual growth, however, lies in the opposite direction. We begin by distrusting what we already believe, by actively seeking the threatening and unfamiliar, by deliberately challenging the validity of what we have previously been taught and hold dear. The path to holiness lies through questioning everything."
