Based on Chapter 45, how is the power of the Guru described in relation to a devotee's life and goals?

According to Chapter 45, the power of the Guru is paramount, even surpassing the ultimate goal of Moksha (liberation). The text states that by serving the holy water of the Guru’s feet, Moksha can enter one's home unknowingly. The Guru's mercy is what makes worldly life happy, renders the impossible possible, and can ferry a devotee across the ocean of existence in a moment. Chapter 45 further explains that it was the Guru, Sai Baba, who initiated the writing of the Satcharitra, thereby setting His devotees on the true path and leaving behind this literary form for their remembrance and spiritual benefit.
