What is the single most important principle or emotion that Sai Baba values, according to Chapter 44?

The source material from Chapter 44 unequivocally states that love is the supreme principle for Sai Baba. The text explicitly notes that "Sai is filled inside and outside of all beings" and that "Except for love alone, He has no other liking." This core value is described as a "supreme nectar" that constantly flows from his mouth, highlighting his "intense love for the devotees." His pained reaction to people hurting one another and his pleasure with patience further reinforce that love, expressed through kindness and compassion, is the only thing he truly desires from his followers.
