The last questions have to do with the important subject of nibbana. a) What is nibbana  ? b) Where is nibbana ? c) How are you going to see nibbana  ?           (That is, if you believe nibbana  exists.)             These are good questions to ask, because all Buddhists want to end suffering. To end suffering you have to reach nibbana.  We will answer these questions briefly, but when you practice successfully, you will understand better.   What Is Buddhism ? a) What is Nibbana  ?   Nibbana is the object of brief path-moment. Nibbana  is ultimate reality, or the true state of the nature of things. This path-moment that has nibbana as an object, extinguishes defilement and ends suffering. Suffering is 'us' (nama-rupa). If there is no 'us' (nama-rupa) there is no suffering such as old age, sickness, and death, etc, - because there are no Five Aggregates in the state of nibbana. The Five Aggregates are the real suffering (dukkha-sacca).               Each of us is composed of these Five Aggregates: body, feeling , perception, volition, and consciousness. Or more simply, these Five Aggregates are body (rupa)  and mind (nama).  (The last four of the above five are mind.) The Five Aggregates are the truth of suffering (dukkha-sacca, or 1st Noble Truth). Dukkha-sacca  exists but we generally don't see it. It is caused by defilement (craving) and that defilement creates us. That defilement that creates us stays with us a long time - unless something is done about it.
