Quotation sobre Pirkei Avot 3:23

Similarly, our sages taught "judge every man favorably" (Avos 1:6), "receive every person with a cheerful countenance" (Avos 1:15), and "Be very, very lowly of spirit" (Avos 4:4), and "One should always be flexible as a reed and not unyielding as a cedar. This is why the reed has merited to have made from it a quill to write a Sefer Torah, Tefilin and Mezuzot" (Taanis 20b).
