“Bhikkhus, there are these four right strivings. What four? Here, a bhikkhu generates desire for the non-arising of unarisen bad unwholesome states; he makes an effort, arouses energy, applies his mind, and strives.

He generates desire for the abandoning of arisen bad unwholesome states; he makes an effort, arouses energy, applies his mind, and strives.

He generates desire for the arising of unarisen wholesome states; he makes an effort, arouses energy, applies his mind, and strives.

He generates desire for the persistence of arisen wholesome states, for their non-decline, increase, expansion, and fulfillment by development; he makes an effort, arouses energy, applies his mind, and strives.

These are the four right strivings.”

Those who strive rightly
overcome the realm of Māra;
they are unattached,
gone beyond fear of birth and death.

They are contented and unstirred,
having conquered Māra and his mount;
those happy ones have overcome
all Namuci’s armies.
