How does one truly surrender to a Guru like Sai Baba, according to the teachings?

According to the wisdom in Chapter 27, true surrender involves becoming very humble and placing yourself at the Guru's feet, acknowledging that the Guru alone knows what is proper and improper. You should surrender your mind, with all its thoughts and doubts, as well as your power of action to Sai. The text advises placing the entire burden on him and acting according to his commands without any ego. If you work without the pride of saying 'I will do this,' then perfect success is assured. This act of surrender is presented as the way to awaken from the 'sleep of ignorance' and receive the Guru's knowledge.
