You may find it hard to recognize that time is the cause of your suffering or your problems. You believe that they are caused by specific situations in your life, and seen from a conventional viewpoint, this is true. But until you have dealt with the basic problem-making dysfunction of the mind—its attachment to past and future and denial of the Now—problems are actually interchangeable. If all your problems or perceived causes of suffering or unhappiness were miraculously removed for you today, but you had not become more present, more conscious, you would soon find yourself with a similar set of problems or causes of suffering, like a shadow that follows you wherever you go. Ultimately, there is only one problem: the time-bound mind itself.
