The text refers to Sai as the 'Lord of Yoga'. What does this imply about his spiritual practice and state of being?

Chapter 4 explains that being the 'Lord of Yoga' refers to Sai's profound spiritual state of non-duality. He had achieved a state of oneness where the feeling of separation is discarded, and everything, both moving and unmoving, is perceived as Brahman. This realization that 'I am everything' is the eternal majesty of Brahman and leads to supreme devotion and indescribable happiness. Having conquered the difficult-to-cross world, his mind is colored with the form of the Self, and his sole aim is the attainment of the Supreme.
