What exactly is the 'So-ham' attitude that the chapter says Sai Baba is indifferent to?

Chapter 36 does not provide a detailed philosophical explanation of the 'So-ham' concept. It simply characterizes Sai Baba's relationship to it. The text mentions that as the "swan in the lake of the Supreme," he is "indifferent to the 'I am He' (So-ham) attitude." This is used to portray him as a being who transcends ego and the need for self-identification with the divine. Instead of dwelling on this state, he is said to delight in serving those who are liberated, showcasing his nature as an incarnation of truth who remains detached.
