Responsa sobre Salmos 1:1

After washing the hands in the morning, I say asher yazar. Immediately thereafter I recite Elohai neshamah, leaving the benediction al netilat yadayim to be said at the synagogue. After the benediction of the Torah, I add three verses from the Pentateuch (Leviticus, 19:16-18), three verses from the Prophets (Joshua, 1:7-9), three verses from the Hagiographa (Psalms, 1:1-3), and the Mishnah Elu debarim she-en la-hem shiur (Peah 1:1). Thus I indicate that the benediction of the Torah includes the Mishnah. (The other sections tally with the order of our prayer books.)
