If a person struggles in this world to understand the Torah, even if he lacks the capacity to comprehend it, he should not be discouraged.

In the World to Come, when he sits in the Heavenly Academy, he will then be able to understand the Torah with which he struggled in this world. His efforts will be richly rewarded. 

~ R’ Yehudah Hachassid zt”l in Seifer Chassidim
