The Five Khandhas - Khandhas are impermanent

Anything which is khandha does not last; as soon as it has arisen it falls away again. Although khandhas arise and fall away, they are real; we can experience them when they present themselves. Nibbāna, the unconditioned dhamma which does not arise and fall away, is not a khandha.


The ‘visuddhimagga' (XX,96) explains about the arising and falling away of

nāma and rūpa:


There is no heap or store of unarisen nāma rūpa (existing) prior to its  arising.

When it arises it does not come from any heap or store;

and when it ceases it does not go in any direction.

There is nowhere  any depositor 

in the way of a heap or store or hoard of what has ceased.

But just as  there is no store, prior to its arising, 

of the sound that arises when a lute is played, 

nor does it come from any store when it arises,

nor does it go in any direction when it ceased,

nor does it persist as a store when it has ceased,

(''Kindred Sayings'' IV, 197), but on the contrary, 

not having been, it is brought into being owing to the lute,

the lute's neck, and the man's appropriate effort,  

and having been, it vanishes - - so  too all

material and immaterial states (rūpa and nāma), 

not having been, are brought into being,

having been, they vanish.
