Dhamma Verses (Dhammapada, KN 2)

2: The Chapter about Heedfulness – 31
The heedful attain Nibbāna
King Udena had two queens, Sāmāvatī, who was a follower of
the Buddha, and Māgandiyā, who was spurned by the Buddha;
out of jealousy Māgandiyā brought about the destruction of
Sāmāvatī and her five hundred followers, all of whom had
attained stages of Awakening; Māgandiyā and her family, who
were full of defilements, were put to death by the King; when
what had happened was reported to the Buddha he spoke these
verses about them.
21. Appamādo amatapadaṁ, pamādo maccuno padaṁ,
appamattā na mīyanti, ye pamattā yathā matā.
Heedfulness is the deathless state,
heedlessness the state of the dead,
the heedful do not die, (but) those
who are heedless are as if dead.
22. Etaṁ visesato ñatvā appamādamhi paṇḍitā,
appamāde pamodanti, Ar i yānaṁ gocare ratā.
The wise, fully understanding
this in regard to heedfulness,
rejoice in heedfulness, delight
in the domain of Noble Ones.
23. Te jhāyino sātatikā, niccaṁ daḷhaparakkamā,
phusanti dhīrā Nibbānaṁ, yogakkhemaṁ anuttaraṁ.
Those who meditate all the time
constant and firm in their effort,
those wise ones will reach Nibbāna,
the unsurpassed release from bonds.
