There's always so many other reasons not to be in the now. It seems like our whole society is in a constant state of past and future that the now becomes this passive thought. I think that if we are able to realize that we are the activity then we will be less inclinde to look to other events that don't actually exist because they havn't yet happened or they are gone in the past. But the now also sometimes feels like dancing on a pin head. As soon as you have it you lose it and you start thinking or trying to define, you get right back into your grooves and just spin and spin. I think this is less frustraiting when you realize that like water though our thoughts may rain, evaporate, or flow in the ocean that they are all water then we can handle these grooves with the dancing rather than the thinking.
