The source calls Sai the 'Lord of Yoga.' Based on the text, what can you tell me about the type of yoga He embodied?

According to Chapter 4, Sai is referred to as the "Lord of Yoga" who appeared on the Godavari for the sake of uplifting the world. While the provided text does not name a specific school or style of yoga, it describes the profound state He attained through His practice. This state involves discarding the feeling of duality and realizing that everything, both moving and unmoving, is Brahman by nature. The text explains that when one achieves this realization of "I am everything," they attain supreme devotion. This attainment is further reflected in Sai's character, as He had conquered the world, His mind was colored with the form of the Self, and His only aim was the attainment of the Supreme.
