According to Chapter 35, what is the most formidable obstacle on the spiritual path, and how does meeting Sai Baba resolve it?

Chapter 35 of the Sai Satcharitra identifies the most difficult and formidable obstacle on the spiritual path as "pride in one's own path." This pride manifests as a form of intellectual arrogance, leading individuals to believe their way of worship, such as focusing on the formless, is superior. They look down on bowing to saints or giving offerings. The chapter explains that this deep-seated pride is completely dismantled by the powerful experience of having Sai Baba's darshan. Upon seeing Sai, even the most resolute skeptics find their pride dissolving, and they spontaneously surrender, thus overcoming that great spiritual barrier.
