In worlds of difference, how might certain unities be forged for liberation? This presentation pursues this question from the vantage-point of the dialectical tension between Marxism and religion. While some scholars have noted parallels between the two, philosophers of critical realism have aimed to establish a deeper equivalence between Marxism and religion. This presentation, however, considers how an equivalence may be forged by subaltern actors in the context of political struggles—how a religious Marxism might look as a theoretical and political practice. I do this by historically reconstructing the life of “Sufi” Sibghatullah Mazari, a locally influential communist from Pakistan who equated Sufism with Mao-inflected Marxism.
