The Tantraraja as its name implies, is an important work of its class which is, in one of its parts, here published for the first time with a commentary called Manorama by Subhaganandanatha of (as Bhaskararaya in his commentary on the Nityashodashikarnava says) the Kashmir school. The book touches upon all the principal precepts of Tantra, espicially the esotric practices. An account of the Sakta Pithas has also been given in the background of the ethnological divisions of India. New light has been thrown on the origin of bija, mantra and Gayatri occurring in Tantric works.
