Buddha once said:
Follow only the Good and Pure Ones. Associate only with the Clever Ones,
To learn the Truth from these Nobles gives
an advantage like nothing else!
To follow the fools
and thereby copy and
choose mostly the wrong ways,
to not
know any Good Friends, is
often causing only sad misery!
As if one strings rotten fish on a
grass
straw, this
very same grass will soon smell putrid too...
Exactly
so with anyone, who follows a fool!
Or as if one wraps up perfume in a common leaf,
this same
simple leaf will soon smell sweet too! Exactly so with
anybody, who follows a Noble.

good in beautiful Friendship (Kalyānamittatā):
