Chasidut su Giosuè 6:78

In introducing the Beit Yaakov, the foundation of the faith in God, I will say that it is the finest of sifted flour in God’s portion, the culmination of the divine service of our masters and teachers. It contains the teachings and fundamentals established by the shepherds of Hasidism, whose faith and fear of sin preceded their wisdom and understanding. Their teachings contain knowledge clarified from all manner of impurity, wholly refined, and what remains is akin to the service vessels of the Holy Temple. “They shall come into the treasury of God,” (Yehoshua, 6:19), and they are a treasure house of the fear of God.
In conclusion, R. Gershon Henokh has traced the history of Jewish esoteric wisdom from the very creation of man until his own day – a roller-coaster ride of revelation and concealment, of faith and intellect. Underlying all is the movement from above to below, from a transcendent vision of Divinity to its God’s immanent manifestation on earth. This is the messianic process, which strives for the day when “the earth will be filled with the knowledge of God as waters cover the sea” (Isaiah 11:9). It was the goal of the Baal Shem Tov and all his followers, who sought to invest quotidian existence with an awareness of God, and it was realized, above all, in the line of Izhbitzer Hasidism, whose founder and disciples explained the most recondite Kabbalah concepts in a way that was universally understandable and applicable. All this is preparation for Part 2 of the book, in which the author discusses the Izhbiter understanding of the fundamental questions of religious life: faith, providence, love and fear of God, mystical awareness, the commandments, and much more.
