To dwell in the here and now does not mean you never think about the past or responsibly plan for the future. The idea is simply not to allow yourself to get lost in regrets about the past or worries about the future. If you are firmly grounded in the present moment, the past can be an object of inquiry, the object of your mindfulness and concentration. You can attain many insights by looking into the past. But you are still grounded in the present moment.
Nhat HanhMeditation is not to avoid society; it is to look deep to have the kind of insight you need to take action. To think that it is just to sit down and enjoy the calm and peace, is wrong.
Nhat HanhEnlightenment is always there. Small enlightenment will bring great enlightenment. If you breathe in and are aware that you are alive - that you can touch the miracle of being alive - then that is a kind of enlightenment.
