Chapter 48 calls Sai "subservient to his devotees." Can you explain what this means and if the text implies he is also subservient to non-devotees?

Chapter 48 explains that Sai Baba acted as one who is "subservient to his devotees" as a demonstration of his pure love for them. This behavior was a way to "clearly show the multitude of devotees that he is the beloved of his devotees," and this is even described as his vow. However, the text strongly suggests this quality is exclusive to his followers. The same chapter describes Sai as being "Incomprehensible to the non-devotees," while being "accessible to all" who are devotees. This contrast indicates that his nature of being subservient is a loving response to the faith and love of his devotees, and not a quality extended to those who do not approach him with devotion.
