The term "12 Mahajyotirlinga" refers to a group of twelve sacred shrines dedicated to Lord Shiva, considered highly auspicious and revered in Hinduism. Each of these temples represents a different manifestation of Lord Shiva and is believed to be a place where Shiva appeared in the form of a Jyotirlinga (a pillar of light). The Jyotirlingas are considered one of the holiest places of pilgrimage for Hindus.
