Describe the initial interaction between Sai Baba and the Madrasi sannyasi, Vijayananda, as detailed in Chapter 31.

Chapter 31 details a perplexing initial encounter. After the sannyasi Vijayananda had darshan and prostrated at Sai Baba's feet, feeling quite pleased, Baba's disposition suddenly changed. He became outwardly disturbed and instructed the assembly to "send away this sannyasi," declaring that there was "no companionship for work." As a newcomer unfamiliar with Baba's unpredictable nature, Vijayananda was understandably distressed and his mind became troubled by this apparent rejection. Despite this disheartening welcome, he did not leave immediately but chose to sit and continue observing the service, showing a degree of perseverance.
