Babylonian Talmud: Eruvin 95b
מיפלגי ת"ק סבר לצאת בעי כוונה ורבן גמליאל סבר לא בעי כוונה
There was a debate: the first teacher held that in order to fulfill a mitzvah (commandment/ good deed) one needs the proper intention; Rabbi Gamliel held that one does not need the proper intention. [Translation by Hillel and Panim]

Suggested Discussion Questions:

1. What are some actions you do without intentions? What actions do you do with intentions?

2. How does intention affect your actions?

Time Period: Rabbinic (Maccabees through the Talmud)
