Recommended Books on the Path of the Masters, Inner Light and Sound
1) The Philosophy of Liberation: My number one recommended book on Sant Mat is, The Philosophy of Liberation (Philosophy of Salvation). This is "THE Manual of Sant Mat", written from an Indian point of view for devotees of traditional Sant Mat. There is a translation of it online. https://archive.org/details/PhilosophyOfLiberationAManualOfSantMatMysticism

3) Path of the Masters: There is a site where you can download the spiritual classic, Path of the Masters. The PDF File version is quite good. I see they have added some e-book options recently also:

5) The Bijak of Guru Kabir: The Bijak is the real "satsang template" of the Path of the Masters, providing the necessary ethical foundation, inspiration, and basic teachings of the Masters for living a spiritual life, a life of love in this human form, supplying the genuine background, context and principals of the Path. At the following website you'll see excerpts from the three primary sections of the Bijak: the Shabdas, Ramainis, and Sakhis: https://SantMatRadhasoami.Blogspot.com/2019/01/kabir-and-kabir-panth-bijak-anurag.html
