Siman 90

(10.) On Purim, wonders became known to me. Rabbainu o.b.m. answered and said: The Torah [is called] the Name of the Holy One Blessed He — hidden and revealed. At first the Torah reveals its face to the man, and afterwards it hides itself. And one who has a true soul pursues and circles after it and sacrifices himself for it, and he has great longing and intense yearning with self-sacrifice, until he merits for the Torah to be revealed to him. For at first the matter of Purim was revealed to me in smallness and hiddenness [that is, the matter was not revealed to him in complete revelation, only in allusion and mere sparkling], and afterwards Hashem Yisburach helped me — for He Blessed He always helps me — and the matter was revealed to me. And the matter of Purim that was then revealed was concealed and hidden from all the worlds — only in the upper worlds that are very, very far away is this known. For my service on that aforementioned Purim was to rectify the blemish of Korach. And when this was revealed to me, it seemed very strange to me — what connection does Purim have with Korach? — until Hashem Yisburach helped me etc. For there are matters very concealed in the holy Torah, and it was revealed to me that the letters of Purim [pei-vav-resh-yud-mem] are the initial letters of [Leviticus 13:41]: <span class="verse">"v'im mip'at panav yimaret rosho — kareach hu"</span> — "and if from the front of his face his head is shaved bald — he is bald (kareach)" — the aspect of Korach (kareach). [And the rest he did not explain.] Afterwards Rabbainu o.b.m. said that he was unable to sleep that entire night after he told this, because he was pained that he had revealed this. And he said that his consolation was that he had not really revealed anything at all. And in truth, it is not written thus in the Torah — rather it is written thus: <span class="verse">"and if from the front of his face his head is shaved — he is bald (gibeach)"</span> — only before this it is written: <span class="verse">"And a man whose head hair falls out — he is bald (kareach)."</span> And the matters are very concealed and hidden. Fortunate is he who waits for the coming of the Redeemer — then they will attain his holy conversation.
