What is the primary spiritual obstacle discussed in Chapter 35 of the Sai Satcharitra, and how did it affect people's initial perception of Sai Baba?

Chapter 35 of the Sai Satcharitra identifies pride in one's own spiritual path as a "terrible forest" and the most formidable obstacle to contemplating supreme truth. This pride is illustrated through the example of people who worshipped a formless God and were skeptical of saints with form, like Sai Baba. They considered such saints to be merely human and heard stories that Baba asked for Dakshina, which made them question his saintliness. As the chapter explains, these individuals would resolve to visit Shirdi but decided they would not bow or offer any money, believing blind faith was not good.
