Which specific verses from the Bhagavad Gita did Sai Baba reference when explaining the eightfold nature (Ashtadha-prakriti) to the author?

While Sai Baba mentions that the Lord Himself explained the eightfold nature (Ashtadha-prakriti) to Arjuna through the Gita discourse, the specific verses or a detailed exegesis of them are not provided in Chapter 3. The text focuses on Baba's own explanation, where He states that whatever has name, form, or shape, both moving and unmoving, is His play as this eightfold nature. As Chapter 3 explains, He identifies Himself as being omnipresent, filled in all directions and within all objects of the universe.
