The pearls of the pilgrim, most of them unpublished, others taken from the twenty or so books he has published, show the many facets of the One Truth that Frithjof Schuon has exposed throughout his life. He was, and remains today, an eminent spokesman for the Sophia perennis, the eternal and universal wisdom at the heart of all the great spiritual heritages that humanity has known throughout the ages. It is to the most secret of pilgrimages that these Pearls invite us: that which leads to our own heart, the seat of immanent knowledge.
