Krishnamurti like all true rishis and philosophers, based his saying on seeing. With him the emphasis was always on the perception rather than thinking. Almost in every engagement - even in personal conversations this was often the case - sometimes practically in the middle of a sentence he would say, 'Now listen to the birds' or 'Look at the clouds'. Th mind putting two and two together, would thus be invited to look. One was literally brought back to one's senses.
