We mostly spend [our] 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.
