Yoni in the context of "Annamalaiyar Temple"

A lingam (IAST: liṅga, lit. "sign, symbol or mark"), sometimes referred to as linga or Shiva linga, is an abstract or aniconic representation of the Hindu god Shiva in Shaivism. The word lingam is found in the Upanishads and epic literature, where it means a "mark, sign, emblem, characteristic", the "evidence, proof, symptom" of Shiva and Shiva's power.

The lingam of the Shaivism tradition is a short cylindrical pillar-like symbol of Shiva, made of stone, metal, gem, wood, clay or precious stones. It is often represented within a disc-shaped platform, the yoni – its feminine counterpart, consisting of a flat element, horizontal compared to the vertical lingam, and designed to allow liquid offerings to drain away for collection.

Kamakhya Temple (Rajbanshi: Kāmākhyā moṇḍir; Assamese: kamakhya mondir) is a Hindu temple at Nilachal hills in Guwahati, Assam is one of the oldest and most revered centres of Tantric practices, dedicated to the goddess Kamakhya. The temple is the center of the Kulachara Tantra Marga and the site of the Ambubachi Mela, an annual festival that celebrates the menstruation of the goddess. Structurally, the temple is dated to the 8th-9th century with many subsequent rebuildings—and the final hybrid architecture defines a local style called Nilachal. It is also one among the oldest 4 of the 51 pithas in the Shakta tradition. An obscure place of worship for much of history it became an important pilgrimage destination, especially for those from Bengal, in the 19th century during colonial rule.

Originally an autochthonous place of worship of a local goddess where the primary worship of the aniconic yoni set in natural stone continues till today, the Kamakya Temple became identified with the state power when the Mleccha dynasty of Kamarupa patronised it first, followed by the Palas, the Koch, and the Ahoms. The Kalika Purana, written during the Pala rule, connected Naraka, the legitimizing progenitor of the Kamarupa kings, with the goddess Kamakhya representing the region and the Kamarupa kingdom.
