From Evelyn Underhill, A Guide to Prayer, The Spiritual Life" at page 320:
“Any spiritual view which focuses attention on ourselves, and puts the human creature with its small ideas and adventures in the centre foreground, is dangerous till we recognize its absurdity. …We mostly spend those lives conjugating three verbs: to Want, to Have, and to Do. Craving, clutching, and fussing, on the material, political, social, emotional, intellectual – even on the religious – plane, we are kept in perpetual unrest: forgetting that none of these verbs have any ultimate significance, except so far as they are transcended by and included in, the fundamental verb, to Be: and that Being, not wanting, having and doing, is the essence of the spiritual life.”
