I. A Rasha cannot really internalize the revelation received by learning Torah:^[1]

Even a person who is completely wicked is able to draw G-dliness upon his G-odly soul while he is involved in Torah learning. Nonetheless, on him it says in Tehillim “To the wicked G-d says why do you speak of my commands?” The reason for this is because the effect of his Torah learning is crippled, as although he is able to draw G-dliness down below onto his G-dly soul during his Torah learning, nonetheless he is unable to internalize this revelation within his soul and it remains in an encompassing manner. Accordingly, it is found that his G-dly soul does not benefit from the revelation that is elicited as a result of his Torah learning.
