Siddha Yoga was founded by Swami Muktananda (1908-1982) in 1961. the movement quotes and comments on ritual and philosophical texts of the Veda, Vedanta, Saiva Agama and Tantra and have given special prominence to texts of Kashmiri Shaivism. Siddha Yoga seems to have an open or an emerging cannon of scripture that is determined by the guru’s assessment of what the devotees need.
