Frasi di Sana'i di Ghazna

“He who knows not his own soul, how shall he know the soul of another? and he who only knows hand and foot, how shall he know the Godhead? The prophets are unequal to understanding this matter; why dost thou foolishly claim to do so? When thou hast brought forward a demonstration of this subject, then thou wilt know the pure essence of the faith; otherwise what have faith and thou in common? thou hadst best be silent, and speak not folly. The learned talk nonsense all; for true religion is not woven about the feet of everyone.”
