Voice of the true prophets

  We did not heed the voice of the true prophets, the voice of the best of the sages of all the generations, the voice of the righteous and the Hassidim, the sages of morals, the sages of study and secrets, who were crying out loudly that the river of the practical study alone will ultimately run dry, unless we constantly draw into it the water of the wisdom of Kabbalah.
