We cannot be in this moment here/now and be thinking about, engaged with, in, some other moment, past or future. To be here/now is to be here/now. Period. Empty of everything but what is happening here/now. How often are you ever there? For how long? How long can you be here/now? Before shifting over to some other place to be? This moment has to be the only moment if we are going to offer here what the moment needs from us. We cannot do that absent-mindedly. We cannot be somewhere else and do here what needs to be done, when, where, and how it needs to be done. Do you want your dentist to fill a cavity while watching TV? It takes practice to be still, silent, and empty in order to be here/now, present, open, aware of what is happening and what needs to be done about it, moment by moment, in each situation as it arises. What is the nature of your practice? How often do you practice? For how long?
