Spiritual Discourses is a translation of the Persian book Guftar-ha-ye Ma'navi by the great Muslim thinker and reformer Ayatullāh Murtadā Mutahhari. This book is a collection of thirteen lectures delivered by the Ayatullah on various topics, such as the criteria for humanity, the school of humanity, spiritual freedom, nobility and magnanimity of spirit, worship and prayer, repentance, migration and ijthād, and belief in the unseen. All these lectures are on spiritual issues, so they are gathered in one collection.
