Can you explain the philosophical concept of Sai Baba moving from 'Nirguni' to 'Saguni' as described in Chapter 30?

Chapter 30 provides a concise yet profound explanation of this transition. It states, "In the beginning, You reside as the formless (Nirguni). Then, through the qualities of devotees' devotion, You draw the formless into form with attributes (Saguni)." This describes a fundamental concept in Indian philosophy where 'Nirguni' represents the absolute, unmanifested, and attribute-less divine reality. 'Saguni' represents the divine manifested in a form with qualities that devotees can perceive, worship, and relate to. According to this chapter, it is the power of the devotees' love and devotion that compels the formless Absolute to take on a tangible, accessible form like that of Sai Baba, the 'crest-jewel among saints'.
