should you encounter lust in 'real life , ' rest assured that it will not be through the eyes of a visionary , for lust is not an observable outer phenomenon , but an intense inner force that comes not as a friend with glad hand extended , nor as a lover with open heart , but as a furtive spy in the night , nostrils flared , eyes raging , intent on grabbing your total attention by its primordial root and shaking you back to your primitive past .
