The text refers to Sai as a 'Lord of Yoga.' What does this title signify about his spiritual state?

Referring to Sai as the 'Lord of Yoga' highlights his profound spiritual attainment rather than a specific type of physical practice. As described in Chapter 4, his yoga was the realization of ultimate oneness. He had completely discarded the feeling of duality, viewing all of creation, both moving and unmoving, as Brahman. This state is one where the individual realizes 'I am everything,' leading to supreme devotion and the absence of fear or enmity. Chapter 4 further elaborates that his mind was perpetually 'colored with the form of the Self,' and his singular aim was the 'attainment of the Supreme,' demonstrating a complete mastery over the self and the world.
