This book embodies Abir Bazaz's enduring engagement with the poetic corpus of Nund Rishi. By unpacking the cryptic philosophical and philological riddles in the poems, Bazaz unearths a negative theology in Nund Rishi's mystical poetry. He argues convincingly that the themes of Islam, Death, the Nothing and the Apocalyptic in these poems reveal an existential politics. Bazaz further suggests that the apophatic style of Nund Rishi's poems is in turn mirrored in mystical poetry across South Asia and the larger Indo-Persian world.
