Worthy,
quite Wise and Virtuous:
The
Blessed Buddha once said:
Worthy, wise
and virtuous:
Who is energetic, and not indolent,
In misfortune unshaken,
Flawless in manner, and intelligent,
Such one will honour gain.
Utthanako analaso,
Apadasu na vedhati,
Acchinnavutti medhavi,
Tadiso labhate yasam.
Digha Nikāya
III 273
