1) Listen to this morning's class, "The 'Freedom' of Torah," here. Follow along with the sources here.
2) Read R. Pinchas Stolper's English translation (from his Living Beyond Time) of the passage from Pahad Yisshak (Shavuot 21:1) that we read here.
3) Read a previous - and different - explanation that I proposed to the facet of "freedom" inherent in Torah study, here.
