This work, written towards the end of Al-Ghazali's career as a philosopher, advances the idea that reason can serve as a connection between the devout and God. Exploring the boundary between philosophy and theology, it seeks to understand the role of reality in the perception of the spiritual.

Abu Hamid Muhammad al-Ghazali's philosophical explorations covered nearly the entire spectrum of twelfth-century beliefs. Beginning his career as a skeptic, he ended it as a scholar of mysticism and orthodoxy. The Niche of Lights, written near the end of his illustrious career, advances the philosophically important idea that reason can serve as a connection between the devout and God. Al-Ghazali argues that abstracting God from the world, as he believed theologians did, was not sufficient for understanding. Exploring the boundary between philosophy and theology, The Niche of Lights seeks to understand the role of reality in the perception of the spiritual.
