According to Chapter 35, what is the biggest obstacle on the spiritual path, and what stories does the chapter introduce?

Chapter 35 of the Sai Satcharitra identifies "pride in one's own path" as a "terrible forest" and the most formidable obstacle for a spiritual seeker. It describes people who are proud of their belief in a formless God and look down upon saints like Sai Baba who have a form and accept offerings. After explaining how even these proud individuals surrender to Sai upon meeting him, the chapter indicates the stories that will follow. As mentioned in the text, it will narrate the experience of Balaji Nevasakar with Sai's sacred ash (Udi) and a story about how a serpent was treated with love, viewing it as a manifestation of Sai himself.
