Worthy, Wise and Virtuous:

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