Can you explain the linguistic or etymological origins of the term 'Sahaj-sthiti' as detailed in Chapter 50?

Chapter 50 does not provide a linguistic or etymological analysis of the term 'Sahaj-sthiti.' It uses the term to define an experiential spiritual goal, not to discuss its origins. The chapter describes 'Sahaj-sthiti' as a "natural state" where "the pulse of 'I' and 'You' does not exist." The text emphasizes attaining this state of non-dual devotion as a primary objective for the devotee, stating, "We should attain that non-dual devotion; this is what we ask of Sai." The focus is entirely on the spiritual meaning and attainment of this state, not on its philological background.
