In his Mosaic essay on Judaism and yoga, Menachem Wecker strongly urges faithful Jews to be wary of a practice that is now a ubiquitous part of the American culture of wellness and fitness. The reason: it is impossible to disentangle yoga’s current, secularized iteration from its millennia-old links to both Hindu and Buddhist spiritual traditions. Yoga teachers, Wecker writes, “indisputably employ a vocabulary, and inculcate physical positions, that derive from centuries-old religious worship”—the worship, in short, of false gods.
