One who wears the stainless robe
who's yet not free from stain,
without restraint and truthfulness
for the stainless robe's unfit.
-Dhammapada Verse 9
Explanation: A monk may be stained by defilements, bereft of self-control and awareness of reality. Such a monk, though he may wear the 'stained cloth' ( the monk's robe which has been specially coloured with dye obtained from wild plants), he is not worthy of such a saintly garb.
