Tantrasamuchaya of Chennas Narayan Nampoothiri (1427-28 A.D.) is the most influential and widely practiced ritual manual of Kerala. It primarily deals with the temple-oriented rituals ranging from construction of a new temple to the installation and expiatory rituals. There are two Sanskrit commentaries on it, called Vimarsini and Vivarana, written by his son and disciple respectively.

               As a part of our collective effort to make all the texts related to Kerala Tantra freely available to scholars worldwide, we are uploading this commentary chapter by chapter. It is uploaded in Devanagara lipi along with Vivarana & Vimarshani commentaries.
