Synopsis The Tantra of Svayambhu or Savyam-bhuvasutrasamgraha is the thirteenth in the Traditional list of the 28 Agamas of Saivasiddhanta. One of the oldest Acaryas of this school of Saivism, Sadyojyoti has composed a commentary on its vidyapasda section. The subjects dealt with are pasu, the bound soul; pasa, the bond; anugraha, God's grace and adhvan, the way to liberation. Sadyojyoti has taken definite and extreme positions on the philosophical problems raised by these concepts. He emphasizes their ritualistic foundation which is the true spirit of Tantric literature and the core of the Saiva religion. The text of his commentary is critically edited here and published with an English translation.
