Negativity and Suffering Have Their Roots In Time

I was really struck by this particular passage in a book I'm reading. Please consider these thoughts...

All negativity is caused by an accumulation of psychological time (the focus on past or future, not clock time) and denial of the present. Unease, anxiety, tension, stress, worry–all forms of fear—are caused by too much future, and not enough presence. Guilt, regret, resentment, grievances, sadness, bitterness and all forms of nonforgiveness are caused by too much past, not enough presence. Most people find it difficult to believe that a state of consciousness totally free of all negativity is possible. And yet this is the liberated state to which all spiritual teachings point. It is the promise of salvation, not an illusory future but right here and now.

You might 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 from 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-bounded mind itself.
