Can you summarize the key metaphors used in Chapter 27 to describe Sai Baba and the path of devotion?

Chapter 27 of the Sai Satcharitra employs several powerful metaphors to illustrate the nature of the Sadguru and devotion. The Sadguru is described as a 'wish-fulfilling tree of liberation' and an 'ocean of self-knowledge,' highlighting his role in granting spiritual freedom and wisdom. The text also compares taking a dip in this 'one ocean' to achieving the merit of all pilgrimages. Devotees' longing for the Guru's stories is likened to the Chatak bird's intense craving for rainwater. As explained in Chapter 27, worldly life and attachments are dismissed as 'momentary Maya, like the shadow at noon,' emphasizing their transient nature compared to the eternal truth found through the Guru.
