Kamapitha was one of the four Kamarupa Pithas, the geographical divisions of ancient Kamarupa. 16th-century work Yogini Tantra
gives the boundaries of Kamapitha and other three pithas, the same work
which gives boundaries of ancient Kamrup kingdom as well.
Sources defines Kamapitha as Guwahati area up to the Manas River, an area also known as Kamrup. Pratap Chandra Choudhury, has no difficulty in accepting that Kamapitha of Tantras, is nothing else than Kamrup and Kamakhya area of Gauhati itself. Kamarupa Anusandhan Samiti, also presses that it is rather absurd, to exclude Kamakhya from the region called Kamapitha.
It form the waist on the position of the genital organ (kama),
justifying its name. Kamapitha also known as Kamrup, is important Shaktipeeth and pilgrimage center, due to presence of ancient Kamakhya Temple, relating to legends of goddess Kamakhya. Kamapitha is heart of ancient Kamrup kingdom, with presence of two major capitals out of three namely Pragjyotishpura and Durjaya.
It is believed that, each pitha of Kamrup is in charge of respective deities. Kamakhya is said to be the deity, which governs Kamapitha, whereas Jalpisa looks after Ratnapitha while Dikkarvasini takes charge of Saumarpitha.
