Пост آن کس که بداند و بداند که بداند

آن کس که بداند و بداند که بداند اسب خرد از گنبد گردون بجهاند آن کس که بداند و نداند که بداند آگاه نمایید که بس خفته نماند آن کس که نداند و بداند که نداند لنگان خرک خویش به منزل برساند آن کس که نداند و نداند که نداند در جهل مرکب ابدالدهر بماند — ابن یمین فَرومَدی He who knows truth, and knows his mind is clear, Shall spur the steed of wisdom past the sphere. He who knows much, yet knows not what he keeps, Rouse him to waking ere he longer sleeps. He who knows little, yet knows his need is great, Will guide his limping donkey to the gate. He who knows not, nor knows his mind is blind, In compound ignorance shall stay confined. — Ibn Yamin Faryumadi
