According to Chapter 12, what is the Guru's role in helping devotees, especially those who are considered 'ignorant'?

Chapter 12 portrays the Guru, exemplified by Sai Baba, as a compassionate guide for all, especially those who are ignorant of the spiritual path. The text describes how some people 'wallow in the desire for wife, son, and wealth,' and a saint might even 'devote his life to them.' The Guru's primary role is to foster firm faith, which is presented as the key to spiritual progress. As Chapter 12 states, by 'placing faith at the feet of saints, the ignorance of the ignorant is destroyed.' The Guru is like the 'sun for the darkness of ignorance,' lovingly caressing the innocent and helping them cross the 'ocean of worldly existence' through the power of devotion, not intellectualism.
