Based on Sapatnekar's story in Chapter 48, how did Baba use apparent harshness to ultimately bestow grace upon a devotee?

Sapatnekar's experience in Chapter 48 demonstrates that Sai Baba's methods could appear severe but were ultimately compassionate. The repeated "Chal Hat" rebukes pushed Sapatnekar into a state of deep introspection and distress, forcing him to question his past karma and his initial doubts about Baba. This trial purified his heart and strengthened his resolve, as he decided to wait patiently for grace. His perseverance was rewarded when he approached Baba, held his feet, and was then shown Baba's omniscience through the narration of his life story. This shows Baba's method of testing a devotee's faith to its limit before showering them with profound grace and a deeper spiritual understanding.
