Jewish books are for the Jew, And Jew Messiahs, too. But if you're not of Jewish blood, How can they be for you? To make an Idol of a book Is poison for the brain; A dying God upon a cross Is reason gone insane. Beware of all the Holy books And all the creeds and schools, And every law that man has made And all the golden rules. "Laws" and "rules" imposed on you From days of old renown, Are not intended for your "good" But for your crushing down. Then dare to rend the chains that bind And to yourself be true. Dare to liberate your mind, From all thing , old and new. Always think your own thought, All other thoughts reject; Learn to use your own brain And boldly stand erect.
