Reb Areleh wrote that Hashem grants those who are seeking him a gift. Amalek doesn't wish to remove our faith, rather to lessen it. In every generation Amalek has a different method to wage war with the Jews. Whoever wanted to be in the room where he wrote his sefer needed to go to the mikveh first. He wrote all of his seforim in weeks without any sources in front of him. It was said if we focus on studying his seforim, there's a 100% chance it will change our life.
