According to a tradition which developed after Basava's time, "Veerashaivism" was transmitted by five "Panchacharyas", namely Renukacharya, Darukacharya, Ekorama, Panditharadhya, and Vishweswara, and first taught by Renukacharya to sage Agasthya, a Vedic seer. A central text in this tradition is Siddhanta Shikhamani, which was written in Sanskrit, and gives an elaboration of "the primitive traits of Veerashaivism in the Vedas and the Upanishads" and "the concrete features given to it in the latter parts (Uttarabhaga) of the Saivagamas." While Veerashaivas regard the "Siddhanta Shikhamani" to predate Basava, it may actually have been composed in the 13th or 14th century, post-dating Basava.
