Sa?kara is well known for his Advaitika philosophy, expounded through his commentaries on the Brahma-sutra, Upani?ads and the Bhagavadgita. However, his independent works on Tantrika philosophy are not commonly acknowledged and appreciated. This book seeks to analyze and understand the metaphysical and conceptual framework and nuances of his Tantrika philosophy, especially with reference to his Saundarya-lahari. Apart from this, it also examines the compatibility of this Tantrika framework with the Advaitika framework, as elaborated by Sa?kara and Gau?apada. The course of this enunciation and examination also presents a lucid discussion of the Sri-vidya tradition of Tantra, as well as the significance of devotion (bhakti) in Sa?kara's philosophy. It is a must read for understanding Sa?kara's philosophy holistically.
