At Savatthi the Blessed Buddha said this:
Bhikkhus, without directly knowing & completely comprehending The All, without being
disgusted with it and leaving it all behind, one is incapable of eliminating any suffering...
Without directly knowing & completely comprehending the eye, forms, ear, sounds, nose,
smells, tongue, tastes, body, touches, mind, ideas and all metal states, any consciousness
all forms of contact and whatever kind of feeling arised caused by such sense-contacts,
without becoming disgusted with it, without relinquishing it all, & without letting it all go,
one is incapable of eradicating any suffering irreversibly...
This, friends, is that All, which without directly knowing, without completely comprehending,
without being disgusted by & without leaving, one is incapable of eliminating all suffering...

Comments:
The radical rationality of the Buddha-Dhamma here shines forth, wiping all empty babble away!
Since what is suffering? The five Clusters of Clinging are suffering! Body, Feeling, Perception,
Construction & Consciousness and thus also the 6 senses, their 6 objects, & 6 kinds of consciousnesses,
their 6 kinds of contact and their 6 kinds of feeling are all suffering... Why is all that suffering?
Because all that is inherently impermanent and thus always lost, decaying, & vanishing by itself...


Clinging is an intensified form of Craving...
Craving is the Cause of Misery!!!
