Naishkarmyasiddhi is a famous Advaita classic of Shri Sureshvaracharya, an immediate disciple of Adi Shankaracharya, and is said to be a manual embodying the quintessence of Vedanta. The work is held in such high esteem in the tradition of Advaita that it is quoted not only by every important Advaita writer but also by the critics of the Advaita philosophy. The author himself says that the work ‘purports to set forth the epitome of the essence of the entire Vedanta’. This book contains the original Sanskrit text, its English translation, and exhaustive notes.
I am the thread that runs through all these pearls, and each pearl is a religion or even a sect thereof. Such are the different pearls, and God is the thread that runs through all of them; most people, however, are entirely unconscious of it.
-Swami Vivekananda
