"The Secrets of the Self (Asrar-i Khudi) — A Philosophical Poem" by Iqbal is a collection of poetry published in 1915. Written in Persian, this work explores the philosophy of "Khudi" or "Self"—the divine spark within every human being. Iqbal charts a spiritual journey of transformation, comparing it to a seed breaking through its shell to reach its fragrance. Through various stages, the self must develop and strengthen to achieve perfection and self-realization, ultimately enabling one to become God's vicegerent on earth.
