The text describes the Sadguru as formless and beyond qualities. Why then does he manifest in a form like Sai?

Chapter 1 addresses this philosophical point by explaining that the one who is originally formless and beyond qualities takes on a form for the specific welfare of devotees. This manifestation, such as 'this Sai of pure qualities,' is an act of grace. The text further elaborates that this duality allows for the 'joy of devotion.' Citing the Shruti 'The one does not enjoy alone,' it suggests that the formless Brahman desires to 'be many' out of love, creating a divine play between God and devotee. This loving relationship, which requires separate forms, would be impossible in the state of pure, non-dual oneness.
