Indologist F. Otto Schrader was among early scholars who studied Lingayat texts and its stand on metempsychosis. According to Schrader, it was Abbe Dubois who first remarked that Lingayatism rejects metempsychosis – the belief that the soul of a human being or animal transmigrates into a new body after death. This remark about "rejecting rebirth" was repeated by others, states Schrader, and it led to the question whether Lingayatism is a religion distinct from other Indian religions such as Hinduism where metempsychosis and rebirth is a fundamental premise. According to Schrader, Dubois was incorrect and Lingayat texts such as "Viramahesvaracara-samgraha", "Anadi-virasaivasara-samgraha", "Sivatattva ratnakara" (by Basava), and "Lingait Paramesvara Agama" confirm that metempsychosis is a fundamental premise of Lingayatism. According to Schrader, Lingayats believe that if they live an ethical life then this will be their last life, and they will merge into Shiva, a belief that has fed the confusion that they do not believe in rebirth. According to R. Blake Michael, rebirth and ways to end rebirth was extensively discussed by Basava, Allama Prabhu, Siddharameshawar and other religious saints of Lingayatism.
