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 novellae 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, Iggeres HaKodesh 26, 145b)
