How does Sai Baba's detached nature relate to the act of giving Udi and blessings?

Chapter 35 provides insight into Sai Baba's divine nature, describing him as being completely beyond duality. He experiences 'no joy in being worshipped, nor sorrow in being insulted,' remaining in a state of perfect detachment. Despite this, as the 'cloud of mercy,' he never disregards anyone. The act of giving Udi Prasad is a manifestation of this grace. While he himself does everything, he maintains an outward detachment. The Udi, given as a blessing and permission to leave, is a tangible sign of his underlying mercy and his wonderful power to attach devotees to his feet, an act described as one of his inscrutable deeds.
