This is credited to Rabbi Israel Salanter.
The blog, the BlackBerry, the email are all vacuums, begging for content. Yet so often there is far more utility in shutting up; perhaps this is why Rabbi Shimon Ben Gamliel says in the Mishna, “All my days I grew up among sages, and I have found nothing greater for a person than silence” (Ethics of the Fathers, 1:17).
Is there a greater test, especially in our time, for the verbally facile, the spiritually agitated, the spirit seeking connection?
UPDATE: Turns out I used a version of that quote before.
