At Savatthi the Blessed Buddha said this:
Bhikkhus: Whatever desire & lust there is for form, feeling, perception,
mental construction and consciousness, whatever greed, urge and craving,
whatever engagement, entanglement and clinging, any habitual addiction,
obsession, and underlying tendency there is for form, feeling, perception,
mental construction and consciousness, overcome, cut and eliminate it all!
Then all form, feeling, perception, mental construction and consciousness
will be overcome & conquered, cut off at the root, made like a palm stump,
completely destroyed, so that they are unable to ever re-arise again...
This - only this - is the End of all Suffering...!
Craving => Clinging => Fear => Panic => Suffering!
More on this thorny Craving causing
Craving can be cut due to the neuro-plasticity
