There three kinds of Suffering (Dukkha)

There are these three kinds of Suffering (Dukkha):

The Blessed Buddha once said: Bhikkhus, there are these three kinds of suffering. What three?

The Suffering caused by painful feeling...
The Suffering caused by construction...
The Suffering caused by change…

These are the three kinds of suffering!This Noble 8-fold Way is to be developed for the direct experience of all three kinds of suffering, for the full understanding of them, for their complete elimination, and for their final overcoming, abandoning and leaving all behind…The Noble 8-fold Way is to be developed for ending suffering!!!

Comment:The first kind of suffering due to painful feeling, whether mental or bodily, is fairly obvious…
The second suffering is things disguised as pleasure, which become suffering when falling apart…
The third kind of suffering is when a pleasant or neutral object inevitably changes and decays…
