Studying the Concealed Torah Is Preferable to the Revealed Torah
Hence the Braita warns us (Hulin 24) to not wait [for our correction by the Light of the revealed Torah] longer than five years [of studying].
Moreover, Rabbi Yosi says that only three years are quite sufficient to be granted the wisdom of the Torah….
If one does not see a good sign within that length of time [from the time when he began to seek similarity with the Creator], one should not fool himself with false hopes and deceit [while studying the revealed Torah], but know that he will never see [in his studies] a good sign [attain correction].
Hence, one must immediately find himself a good tactic by which to succeed in achieving Lishma [the property of bestowal] and to be granted the wisdom of the Torah.
…The surest [easiest] and most successful tactic is the engagement in the wisdom of Kabbalah. One should leave one’s hand entirely from engagement in the wisdom of the revealed Torah, since he has already tested his luck in it and did not succeed [in correcting himself]. And he should dedicate all his time to the wisdom of Kabbalah, where his success [in achieving the goal of creation: similarity with the Creator] is certain.
