Translation:Mishnah/Seder Zeraim/Tractate Berakhot/Chapter 3/4/Translation

A baal keri should think about the Shema in his heart [i.e., instead of saying it out loud] and should not recite the blessings,
either before or after.
On food, he makes the blessing after, but not the blessing before.
Rabbi Yehudah says:
He blesses before and after.
