According to the Shulchan Aruch HaRav

According to the Shulchan Aruch HaRav: One who does not innovate their Torah learning and merely reviews, even 101 times, has not fulfilled his obligation to study Torah. (Hilchos Talmud Torah 1:1; 2:2, based on Sicha of the Lubavitcher Rebbe - Eve of the 12th Day of Sivan, 5743; cf Chagigah 3a)

“Supernal beings come to hear the Chiddushim of Torah from those who dwell in this lower world . . . and every Jewish person is capable of revealing hidden wisdom and to introduce new ideas . . . and he is obligated to do so, in order to fulfill the mission of his soul” (Tanya, Iggeret HaKodesh 26, 145b)
