Chapter 30 mentions Sai moving from 'formless' to 'form with attributes'. Based on the text, what does this transition mean and what causes it?

According to the teachings in Chapter 30, Sai Baba's nature encompasses both the formless and the form. The text explains that initially, He resides as the "formless (Nirguni)." However, He is drawn into a "form with attributes (Saguni)" specifically through the qualities of his devotees' devotion. This suggests that the intense love and faith of his followers are the catalysts that cause the absolute, formless divine to manifest in a perceptible, tangible form. This concept underscores the power of devotion in making the divine accessible to the devotee, allowing for a personal relationship with the otherwise attributeless reality.
