The most significant discussion in this volume is about the meaning of the spirit in the Qur'an. The author says that what springs first to mind from the term is the life principle. However, the Qur'an talks about other forms of spirit. Therefore there are both human and non-human forms of spirit.
With this volume, the exegesis concludes. Benedictions be on the blessed soul of Allamah Tabatabai for guiding us in exploring the Holy Qur'an and understanding its deeper meanings.
