What is the 'Yoga of the Supreme Self,' and what kind of detachment is necessary to practice it for one's own salvation?

The 'Yoga of the Supreme Self,' as detailed in Chapter 17, is an experience that belongs only to the wise. It is characterized by a profound detachment from the enjoyment of the fruits of both this world and the next. This practice also involves the renunciation of dualities such as joy and sorrow. To achieve one's own salvation through this path, one must be endowed with Sai's grace. The text suggests that this grace can be attained by respectfully listening to and contemplating his life story, which helps stabilize the heart and acquire the knowledge of the Self.
