At the turn of the millennium, HarperSanFrancisco, a leading publisher of religious and spiritual books, asked Philip Zaleski, editor of the annual The Best Spiritual Writing series, to look back over the twentieth century and compile a list of the 100 best books in the genre. The nominating panel included Spirituality & Practice book review editor Frederic A. Brussat, S&H columnist Thomas Moore, Natalie Goldberg, Rodger Kamenetz, Harold Kushner, Lawrence Kushner, Christopher de Vinck, David Young, Kabir Helminski, Helen Tworkov, Ron Hansen, Joseph Bruchac, Huston Smith, Lawrence Cunningham, and John Wilson.

All the books had to be published in English for the first time in the twentieth century. Stephen Hanselman of HarperSanFrancisco explained that the list, boasting titles from 50 different publishers, "will guide readers to books that will enrich their souls, serve as a reminder of the twentieth century's enduring spiritual legacy, and spark conversation about the blossoming genre of spiritual writing."
