Then what prevents you from seeing and hearing Him? Truly, there is so great a din in your heart, and so much loud shouting from your empty thoughts and fleshly desires that you can neither see nor hear Him. Therefore, silence this restless din, and break your love of sin and vanity. Bring into your heart a love of virtues and complete charity, and then you shall hear your Lord speak to you.
— Walter Hilton, The Stairway of Perfectio
