How does the author describe Sai Baba's divine power and grace in the opening verses of Chapter 20?

The beginning of Chapter 20 is a powerful invocation that extols Sai Baba's divine attributes. The author describes Sai as a "Siddhashram" or an abode of perfected beings, stating that the mere sight of him relieves the "fatigue of worldly life" and drives away the "delusion of existence." He is hailed as the one who provides the "shelter of eternal rest" and ends the cycle of rebirths for his devotees. The invocation also beautifully compares the Guru to the sacred Manasa lake, whose words of grace are like pearls for the flock of pure devotees, who are likened to swans.
