He [Abba Poemen] also said, 'A man may seem to be silent, but if his heart is condemning others he is babbling ceaselessly. but there may be another who talks from morning till night and yet he is truly silent; that is, he says nothing that is not profitable.'-- Sayings of the Desert Fathers
"For us let it be enough to know ourselves to be in the place where God wants us, and carry on our work, even though it be no more than the work of an ant, infinitesimally small, and with unforeseeable results."
-- Abbé Monchanin
