“The greatest sermons are the ones given with a closed mouth and an open heart.”

“… Bringing the very heavens close enough to touch.
It was Zsadist.
His eyes closed, his head back, his mouth wide open, he sang.
The scarred one, the souless one, had the voice of an angel.”

“A batsman given to run-stealing need not open his mouth to gain the reputation of a wit.”

“If I had stopped to listen once or twice
If I had closed my mouth and opened my eyes
If I had cooled my head and warmed my heart
I'd not be on this road tonight.”

“Genuine sincerity opens people's hearts, while manipulation causes them to close.”

“Human nature is, by definition, a talkative one, imprudent, indiscreet, gossipy, incapable of closing its mouth and keeping it closed.”

“Nature has given us two ears but only one mouth.”

“Why is the truth, it would seem, revealed to some and not to others? Is there a special organ for receiving revelation from God? Yes, though usually we close it and do not let it open up: God’s revelation is given to something called a loving heart.”

“We live, we love. These are the choices we are given, to open doors or to close them. It is all we have, and it is enough”

“Oysters open completely when the moon is full; and when the crab sees one it throws a piece of stone or seaweed into it and the oyster cannot close again so that it serves the crab for meat. Such is the fate of him who opens his mouth too much and thereby puts himself at the mercy of the listener.”
