Who is described as the 'incarnation of the knowledge of Truth' who remains detached from events?

Sai Baba is identified as the 'incarnation of the knowledge of Truth.' Chapter 36 elaborates on this by stating that he shows the realization of truth as a witness, yet remains distant and detached from his own name while causing various events to occur. This highlights his paradoxical nature as both the active cause of events and a detached observer, fully embodying the highest spiritual principles and knowledge for his devotees.
