When about twenty years of age, Israel settled in Brody, one of the principal cities of Galicia, and married the sister of the well-known rabbi and Cabalist of the town, Gershon Kutover. Kutover at first tried to interest his brother-in-law in the study of the Talmud, but, finding him entirely indifferent to this kind of mental occupation, the proud rabbi, abashed by his relationship with such an ignoramus, advised Israel to leave Brody. Besht followed the advice, and removed with his wife to a village between the towns of Kuty and Kosovo. He frequently retired to the neighboring Carpathian mountains, where in strict solitude he fasted, prayed, and lost himself in religious speculation. He eked out an existence for himself and his wife by digging clay in the mountains, which his wife carried into the city for sale. According to the Hasidic legend, Israel Besht led this kind of life for seven years. It was a period of preparation for his subsequent calling. At the end of his mystical exploits in the Carpathian mountains, Besht lived in the Galician town of Tlusta, where he occupied minor ecclesiastic positions, acting in succession as melammed, shohet, and cantor of a synagogue. He was universally regarded as an ignoramus, no one being aware of his innermost cravings.
At last, after reaching the age of thirty-six, Besht decided,—by inspiration from above, as the Hasidim believe,—that the time had come "to reveal himself to the world." He began to practice as a Baal-Shem,[198] i. e. as a magician and Cabalist and to cure diseases by means of secret incantations, amulets (kameoth), and medicinal herbs. The figure of a wandering Baal-Shem was not unusual among the Polish Jews of the time, and Besht chose this career, for it subsequently proved a convenient medium for his religious propaganda. He traveled about the towns and villages of Volhynia and Podolia, curing with his herbs and incantations not only Jews, but also peasants and even pans, who had great faith in magic remedies. He won the reputation of a miracle-worker, and was nicknamed the "good Baal-Shem" (in Hebrew, Baal-Shem-Tob). The Jewish masses felt that he was not the ordinary type of conjurer, but a man of righteousness and saintliness. Besht was frequently called upon to foretell the future, and, opening at random the Zohar before him, made predictions as suggested by the holy book. In curing the sick, he resorted not only to herbs and incantations, but also to prayer. While praying, he often fell into ecstasy and gesticulated violently.
Besht became the favorite of the masses. Warm-hearted and simple in disposition, he managed to get close to the people and find out their spiritual wants. Originally a healer of the body, he imperceptibly grew to be a teacher of religion. He taught that true salvation lies not in Talmudic learning, but in whole-hearted devotion to God, in unsophisticated faith and fervent prayer. When he encountered men of learning, Besht endeavored to convince them of the correctness of his views by arguments from the Cabala. But he did not recognize that ascetic form of Cabala which enjoined upon the Jew to foster a mournful frame of mind, to kill the flesh, and strive after the expiation of sin in order to accelerate the coming of the Messiah. He rather had in mind that Cabala which seeks to establish an intimate communion between man and God, cheering the human soul by the belief in the goodness of God, encouraging and comforting the poor, the persecuted, and the suffering. Besht preached that the plain man, imbued with naïve faith, and able to pray fervently and whole-heartedly, was dearer and nearer to God than the learned formalist spending his whole life in the study of the Talmud. Not to speculate in religious matters, but to believe blindly and devotedly, such was the motto of Besht. This simplified formula of Judaism appealed to the Jewish masses and to those democratically inclined scholars who were satisfied neither with rabbinic scholasticism nor with the ascetic Cabala of the school of Ari.
About 1740 Besht chose for his permanent residence the small Podolian town of Medzhibozh. The rôle of sorcerer and miracle-worker gradually moved to the background, and Besht emerged as a full-fledged teacher of religion. He placed himself at the head of his large circle of disciples and followers, who were initiated by him into the mysteries of the new doctrine, not by way of systematic exposition, but rather in the form of sayings and parables. These sayings have been preserved by his nearest disciples, Besht himself having left nothing in writing.
Two ideas lie at the bottom of the "Doctrine of Piety," or the Hasidism, of Besht: the idea of Pantheism, of the Omnipresence of God, and the idea of the interaction of the lower and upper worlds. The former may be approximately defined by the following utterances of Besht:
It is necessary for man constantly to bear in mind that God is with him always and everywhere; that He is, so to speak, the finest kind of matter, which is poured out everywhere; that He is the master of all that happens in the Universe.... Let man realize that when he looks at things material he beholds in reality the Divine Countenance, which is present everywhere. Keeping this in mind, man will find it possible to serve the Lord at all times, even in trifles.
The second fundamental idea is borrowed from the Cabala, and signifies that there is a constant interaction between the world of the Divine and the human world, so that not only does the Deity influence human actions, but the latter exert a similar influence on the will and the disposition of the Deity.
The further elements of the Besht doctrine follow logically from these premises. Communion with God is and must be the principal endeavor of every truly religious man. This communion may be attained by concentrating one's thoughts upon God, and attributing to Him all happenings in life. The essence of faith lies in the emotions, not in the intellect; the more profound the emotions, the nearer man is to God. Prayer is the most important medium through which man can attain communion with God. To render this communion perfect, prayer must be ecstatic and fervent, so that he who prays may, as it were, throw off his material film. To attain to this ecstatic condition, recourse may be had to mechanical contrivances, such as violent motions of the body, shouts, shaking, and so on. The study of Jewish religious legislation is of secondary importance, and is useful only when it succeeds in arousing an exalted religious disposition. From this point of view the reading of ethical books is preferable to the study of Talmudic casuistry and rabbinical folios.
Contrary to the fundamental precept of the Practical Cabala, Besht insists that excessive fasting, the killing of the flesh, and ascetic exercises in general, are injurious and sinful, and that a lively and cheerful disposition is more acceptable to God. What is most important in religion is the frame of mind and not the external ceremonies: excessive minuteness of religious observance is harmful. The pious, or Hasid, should serve God not only by observing the established ceremonies, but also in his everyday affairs and even in his thoughts. By means of constant spiritual communion with God, man may attain to the gift of clairvoyance, prophecy, and miracle-working. The Righteous, or Tzaddik, is he who lives up to the precepts of Hasidism in the highest measure attainable, and is on account of it nearer and dearer to God than any one else. The function of the Tzaddik is to serve as mediator between God and the common people. The Tzaddik enables man to attain to perfect purity of soul and to every earthly and heavenly blessing. The Tzaddik ought to be revered and looked up to as God's messenger and favorite.
In this way the doctrine preached by Besht undermined not only scholastic and ceremonial Rabbinism, but also the ascetic Cabala, emphasizing in their stead the principle of blind faith in Providence, of fervent and inspiring prayer, and, last but not least, the dogma of attaining salvation through the medium of the miracle-working Tzaddik. The last-mentioned article of faith was of immense consequence for the further development of Hasidism, and subsequently overshadowed the cardinal principles of the new movement.
