Western interest in Eastern religions, especially Buddhism, historically coincided with the rise of modern science and the corresponding perceived decline of religious orthodoxy in the West. Put simply: Modern science initiated a deep spiritual crisis that led to an unfortunate split between faith and reason—a split yet to be reconciled. Buddhism was seen as an "alternative altar," a bridge that could reunite the estranged worlds of matter and spirit. Thus, to a large extent Buddhism's flowering in the West during the last century came about to satisfy post-Darwinian needs to have religious beliefs grounded in new scientific truth.
