(based on Berachot 1:104)

Gemara: Be careful with a scholar who unwillingly forgot his Torah knowledge, for the luchot (tablets given to Moshe) and the broken luchot are [both] placed in the aron (ark).

Ein Ayah: This teaches us that since the goal of wisdom is doing good deeds, a scholar who was involved in Torah study and acquired knowledge all his life has acquisitions of justice and straightness. Although he forgot his Torah scholarship, only the details have been lost. The all-inclusive pure concepts that filled his spirit from the great knowledge and study is not forgotten. This resembles something that a person cannot capture in words, yet the inner spirit recognizes the truth of the straight pleasantness according to its value in Torah and fear of Hashem.
