In Book Five of the Masnavi, Rumi develops a framework of absolute divine causality. He establishes that God's power and grace do not depend on pre-existing human capacity or receptivity (qabiliyyat); rather, God's eternal act creates that very capacity out of non-existence. Because creatures have no autonomous, independent capacity, they function merely as instruments in the hand of the Divine. Rumi applies this metaphysical principle to spiritual life, arguing that a true gnostic (arif) recognizes this instrumentality and attributes all actions to God, the Primary Cause, rather than reacting blindly to the creaturely instrument.
