What is the role of a Guru in achieving spiritual understanding, according to the teachings in Chapter 26?

According to the philosophy presented in Chapter 26 of the Shri Sai Satcharitra, the Guru is paramount and uniquely capable of granting the knowledge of Truth to a disciple. The text emphasizes that the illusion of the world dissolves when the time for awakening through the Guru's word arrives. The author offers a prayer to Baba, the Sadguru, to make his intellect turn inward and grant him the ability to discriminate between the eternal and the temporary. The chapter posits that only the Guru can solve the mystery of existence for the devotee, whose intellect is otherwise clouded by false logic and nescience.
