Based on the introductory verses of Chapter 36, what is the philosophical significance of Sai Baba being described as indifferent to the 'I am He' (So-ham) attitude?

The description in Chapter 36 of Sai Baba being "indifferent to the 'I am He' (So-ham) attitude" is philosophically significant because it positions him beyond a key stage of spiritual realization. While 'So-ham' signifies the profound realization of oneness with the Supreme, clinging to this identity can be a subtle form of ego. The text suggests Sai Baba has transcended even this, being a "swan in the lake of the Supreme" who instead "delights in the service of those liberated in Brahman." This implies a state of pure, selfless service that is not attached to the personal attainment of non-duality, but rather uses that realized state to redeem infinite beings, as Chapter 36 explains.
