Can secular spirituality be religiously inspired? the Hasidic legacy in the eyes of skeptics

A trenchant and rather paradoxical Hasidic saying asserts the following: He who believes the tall tales told by the Hasidim may be a fool, but he who does not believe them is a heretic. It turns out that many secular writers have in fact read and examined Hasidic tales sympathetically, without necessarily regarding them as true. But what exactly is the relationship of such non-believers to Hasidism? Can a secularist genuinely connect with texts that seem to be totally immersed in their religious context and driven by specifically religious interests? Can a reader who repudiates the assumptions of the original author (and even of his intended audience) nevertheless engage in a personally uplifting or even spiritually-inspired reading of such texts? Is there a spiritual dimension capable of traversing the barriers of religious doctrine, and penetrating the inner world of the heretic?
