Like Siddhartha, Yasha has led a life of dissipation. In Yasha's case his transgressions consisted of womanizing, excessive alcohol consumption, keeping friends with shady characters, and, finally, burglary and attempted thievery. Suffering a serious injury, the suicide of one of his paramours, and possible imprisonment, Yasha relinquishes his burgeoning career as a magician and tight rope walker in favor of doing deep religious penance. Also, like Siddhartha, Yasha becomes an ascetic. Recognizing himself as a sinner who could easily slip back again to his former ways, Yasha shuts himself off from the world in a most unusual way. Not through any choice of his own, Yasha becomes, "a holy man" with "Jewish men and women (waiting) at (his) window for (his) blessing."
Isaac Bashevis Singer has written a thought-provoking novel of tremendous intensity in a style containing deceptively simple language. Singer's characters are full of human frailties and vulnerability. Yasha, in particular, is always questioning the morality of his intended acts and their possible consequences on others. This is especially so after he escapes into a synagogue (Yasha is a fallen away Jew) and achieves an epiphany of sorts. Yasha learns that he is not evil, after all, but simply human
and, in many ways worthy of love and admiration.
