How does Chapter 30 reconcile the idea of a formless, attributeless God with the necessity of a Guru in a tangible form?

Chapter 30 addresses this theological point by describing a dynamic movement from the formless to the manifest. It posits that Sai, as the supreme reality, initially exists as 'Nirguni' or formless. However, the text explains that it is the very devotion of the devotees that 'draw the formless into form with attributes (Saguni).' This implies that the Guru's tangible form is a compassionate concession to the devotee's need for a focal point for their love and faith. The chapter reinforces this by calling Sai the 'Acharya (teacher) of the assembly of saints' for whom uplifting devotees is an 'unavoidable' task. Thus, the formless Divine takes a form to guide and uplift seekers, making the abstract accessible.
