Kernel of the Kernel - Allamah Sayyid Tabatabai
"In addition to providing a theoretical discussion of spiritual wayfaring, this is also the account of a personal fifty-year spiritual journey by Sayyid Muhammad Husayn Tabataba'i, a
renowned Iranian-Shii scholar and spiritual master. In Kernel of the Kernel, Tabataba'i 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." - taken from Foreward by Sayyid Hossein Nasr
