註釋 Kernel of the Kernel is an authoritative work on Sufism from a Shi'i perspective that is not only fascinating, but also contains much practical advice. In addition to providing a theoretical discussion of spiritual wayfaring, it is also the account of a personal fifty-year spiritual journey by Sayyid Muḥammad Ḥusayn Ṭabāṭabā'ī, a renowned Iranian-Shii scholar and spiritual master. In Kernel of the Kernel, Ṭabāṭabā'ī discusses the doctrinal foundations of spiritual wayfaring as well as processes and stages that an aspiring wayfarer must go through in order to attain spiritual realization. He discusses the relation between the exoteric and esoteric aspects of Islam and clearly demonstrates that these inward and outward dimensions of Islam complement each other. The book also provides information on the Quranic origins of Sufism and its special relations with Shi'ism as well as the role of Shi'i Imams in the spiritual realization of a sincere wayfarer.
