A radically alternative vision of the fakir is given in surviving medieval (Bng. madhya-?ug, Middle Age ) and pre-modern textual sources that predate and coincide with the colonial period, such as the widely influential 17th century Yoga Kalandar text as well as Bul oral traditions deeply influenced by this text's cosmology. This book aims therefore to fulfill three key objectives: 1) to historically situate the Yoga Kalandar text and its practitioners; 2) to describe the distinctly yogic and tantric aspects of its theology, with specific reference to the way the text harmonizes Sufi and Neoplatonic hypostases and ritual theurgy with SCkhya cosmology; and 3) to describe how the text's cosmology was integrated in later colonial and modern forms of indigenous Bengali mystical poetry, especially the Bul songs of Llan Fakir that make numerous creative references to the practices outlined in the Yoga Kalandar and, in a sense, even transcend the text's limitations. As an appendix for reference, a new English simple translation of this text (from Bengali and French critical editions) is provided.
