What is the role of the Guru in overcoming illusion, according to Chapter 26?

According to the teachings presented in Chapter 26, the Guru is absolutely essential for spiritual awakening because only the Guru can bestow upon a disciple the true knowledge needed to see beyond the illusion of Maya. The text states that the visible world is illusory and dissolves with true knowledge, which happens "when the time for awakening through the Guru’s word arrives." The author demonstrates this dependence by praying to Baba to turn his intellect inward and grant him the ability to discriminate between the eternal and the temporary. The chapter emphasizes that the Guru-Soul, who is God, must be pleased for a devotee to realize the true, self-luminous nature of the Self.
