Musar su Isaia 51:1

He should be zealous to seek knowledge of the Torah and knowledge of the Creator, as it is written. "And let us know, eagerly strive to know the Lord" (Hos. 6:3). Thus said the Sages: "Betake thyself to a place of Torah" (Aboth 4:14). And a man should be alert to seek justice, as it is written : "Justice, justice shall you pursue" (Deut. 16:20). And it is written, "Hearken to Me, ye that follow after righteousness, Ye that seek the Lord" (Is. 51:1). It is necessary to be quick in copying out the books which one needs for one's study. When he sees or hears a new thing, he should be alert to write it down and not delay until it is forgotten from his heart.
