Lingam

The lingam (IAST: liṅgaṃ, also linga, ling, Shiva linga, Shiv ling, meaning sign, or symbol) is an abstract or aniconic representation of the Hindu deity, Shiva, used for worship in temples, smaller shrines, or as self-manifested natural objects. In traditional Indian society, the lingam is seen as a symbol of the energy and potential of Shiva himself.
