Friends:

All is by Nature inherently & inevitably Decaying & Vanishing!

At Savatthi the Blessed Buddha said:
Bhikkhus, All is by nature subject to birth... All is by nature subject to ageing...
All is by nature subject to decay & sickness... All is by nature subject to death...
All is by nature subject to trouble... All is by nature subject to corruption...
All is by nature subject to destruction... All is by nature subject to vanishing...
All that is by nature subject to emergence, is also by nature subject to ceasing...
And what, Bhikkhus, is this All, that is by nature subject to birth, ageing, decay,
sickness, death, trouble, corruption, destruction, vanishing, ever arising & ceasing ?
The Eye ... Forms ... Eye-consciousness ... Eye-contact... Whatever feeling arised
caused by eye-contact, that is by nature subject to ever arising and ceasing...
The Ear ... Sounds ... Auditory-consciousness ... Ear-contact...
The Nose ... Smells ... Olfactory-consciousness ... Nose-contact...
The Tongue ... Tastes ... Gustatory-consciousness ... Tongue-contact...
The Body ... Touches ... Tactile-consciousness ... Body-contact...
The Mind ... Thoughts ... Mental-consciousness ... Mind-contact... & whatever feeling
arised caused any contact, that is by nature subject to ever arising and ceasing...
Understanding this, the intelligent noble disciple becomes disgusted with this All ... 
Being thus disgusted produces disillusion... This disillusion induces a mental release!
When detached, the mind remains unagitated! Being utterly imperturbable one attains
Awakening right there & then instantly understands: This mind is irreversibly freed!
Repeated rebirth is ended, this Noble Life is completed, done is what should be done,
there is no state beyond, ever after or even surpassing this ...
