Can you compare the devotion of Sai Baba's followers from London to that of the two gentlemen from Goa as described in Chapter 36?

A comparison between the devotion of followers from London and the gentlemen from Goa is not possible based on the provided text from Chapter 36. The chapter makes absolutely no mention of any followers from London, so there is no basis for the first part of your comparison. While the text does introduce "Two gentlemen from Goa," it does so at the very end of the provided excerpt and has not yet detailed their story or the nature of their devotion. Therefore, as Chapter 36 does not contain information about Londoner devotees and has only just begun the story of the Goan gentlemen, no such comparative analysis can be performed.
