Meaning of Alvars and Nayanars : Some of the earliest Bhati movements(C. sixth century) were led by Alvars (literally meaning of this word is those who are emerged in devotion to Vishnu) and Nayanars (literally meaning of this word is those leaders who were devotees of lord Shiva). The Alvars and Nayanars travelled place to place singing hymns in Tamil (in praise of their god).

Attitude of Alvars and Nayanars towards caste system : Some historians suggest that the Alvars and Nayanars initiated a movement of protest against the caste system and the dominance of Brahmanas or at least attempted to reform the system. To some extent this is corroborated by the fact that bhaktas hailed from diverse social backgrounds ranging from Brahmanas to artisans and cultivators and even from castes considered “untouchable”.

Meaning of Virashaiva : The twelfth century witnessed the emergence of a new movement in Karnataka, led by a Brahmana named Basavanna (1106-68) who was initially a Jaina and a minister in the court of a Chalukya king. His followers were known as Virashaivas (heroes of Shiva) or Lingayats (wearers of the linga).

Attitude of Virashaivas towards caste system : The Lingayats challenged the idea of caste and the “pollution” attributed to certain groups by Brahmanas. They also questioned the theory of rebirth. These won them followers amongst those who were marginalised within the Brahmanical social order. The Lingayats also encoviraged certain practices disapproved in the Dhanmashastras, such as post puberty marriage and the remarriage of widows.
