“Just as a tree, though cut down, can sprout again if its roots remain uninjured, even so this suffering springs up repeatedly if the underlying craving is not eradicated.”
Canonical Pali Original: Yathāpi mūle anupaddave daḷhe, chinnopi rukkho punareva rūhati; Evampi taṇhānusaye anūhate, nibbattatī dukkhamidaṃ punappunaṃ.
— Gautam Buddha
The Awakened One, Founder of Dhamma
Pali Canon: Dhammapada 24.338 on addressing the root psychological causes of suffering rather than treating mere symptoms.
