Virasaivism is a religious movement of Hinduism in India. The adherents are known as Veerashaivas, or more commonly Lingayats. This important sect of Hinduism represents a reform movement attributed to Basavanna in the 12th century. Basavanna lived and taught in what is now Karnataka State. Some believers believe that Basavanna is an incarnation of Nandi, Shiva's greatest devotee. Nandi serves Shiva perpetually as Garuda does for Vishnu.
Lingayats believe in a monotheistic world where Shiva is the supreme deity. They worship Shiva as a lingam. Additionally, Lingayats wear the lingam in a similar way as Christians wear the crucifix. Basavanna attempted to rid society of caste distinctions, although these can be found to a degree in modern Lingayats. Many of the reforms which Basavanna pushed for would be later adopted by Gandhi, Swami Vivekananda, and others. Also, the Lingayats favor gender equality and in fact, have women gurus.
However, unlike practically all Hindus, Lingayats reject the Vedas but rather focus more on the Hindu Agamas, specically, the Shaivite Agamas. Some Lingayats view the Vedas to be polytheistic in nature while the Agamas are strictly monotheistic and devotional in nature.
The term Virasaiva is derived from vira (heroic), and saiva (worshipper of Siva). The term Lingayat is derived from the lingam, or the abstract symbol of Shiva in which God is worshipped without form.
The Lingayats continue to be strong in Karnataka, and play an important role in social and cultural life in the state.
While the linga is a symbol of great importance to all Shaivite sects, it is the central object of all spiritual activity for one in particular—the Lingayats ("bearers of the linga"), also known as the Virasaivas ("heroic Shaivas"), a reformist Shaivite sect prominent in the border regions of Maharashtra and Karnataka in the mid-twelfth century.
Following their leader, each of Basava's disciples wore a linga in a tube fastened to their neck (or to their arm), which took the place of the sacred thread worn by most orthodox upper caste Hindu men.
Otherwise, Lingayats are highly iconoclastic, and the linga is the only symbol they are permitted to acknowledge, since it alone serves as a constant reminder to the devotee that no other focus is necessary.
The Lingayats' belief in a single deity and their concept of bhakti (devotion) as an intuitive and loving knowledge of God show the influence of Ramanuja.
They reject Brahma and the authority of the Vedas; their opposition to child marriage and the ill-treatment of widows anticipated the social reform movements of the 19th century.
To the Lingayat community, he is a posterboy in a state which has sharply divided caste rivalry with the Vokkaligas.
