Kerala Tantra is a regional phenomenon, which is an offshoot or synthesis of Saiddhantika and Pancaratra tantric ritual rites. It is a tradition deeply rooted within the Vedic ritualistic fold and characterized by Smarta-Pauranika beliefs and customs. This volume is a general, but a serious and in-depth study of distinct temple ritual cult of Kerala. Kerala Tantra still remains to be a less explored subject. There is no exclusive study on the ritual peculiarities of Kerala Tantra. This book focuses on filling that gap covering extensively the prominent characteristics of the unique ritual cult of Kerala. The data presented in the book are based on many unpublished and less-known, but authentic manuscripts of late medieval period, and interviews with previous and current generations of tantrins and their testimonies. It covers the great traditions of Tantra, Kerala Tantra, and transmission of tantric knowledge through formal and informal methods. It also talks about the institutionalization of Tantric education, taking a cue from the context of Vedic and Sanskrit education of Kerala.
