Most people confuse the "now" with what is happening to them in the now. Actually what is happening to you now has nothing to do with the present moment itself. If you were to suddenly die the present moment would remain. The problem occurs when we attach in our minds with what is happening to "us" presently. This is simply a mental construct that we have created ourselves. It is much like a grievance, either real or imagined. If we attach to grievances we are constantly inflicting suffering on ourselves, not the other party.
