Seneca · On the value of advice
Letters 94.42
“What is the point of this remark?” you ask. It is, that good precepts, often welcomed within you, will benefit you just as much as good examples. Pythagoras declares that our souls experience a change when we enter a temple and behold the images of the gods face to face, and await the utterances of an oracle.
Seneca, Letters to Lucilius 94.42, translated by Richard Mott Gummere
