Can you explain the power of Sai's grace as described in Chapter 30 of the Sai Satcharita?

Chapter 30 delves into the profound and transformative power of Sai's grace. The text asserts that when Sai bestows His grace, the recipient 'attains inconceivable great power.' This power is not merely worldly but includes the highest spiritual knowledge, described as the 'wealth of discrimination between Self and non-Self.' The author directly attributes the auspicious and beneficial nature of the Sai Satcharita itself to this grace, calling the text a 'bestower of welfare.' It is this faith in Sai's compassionate grace that stilled the author's wavering mind and allowed him to write, seeing Sai as the 'capable lamp of knowledge' who destroys the darkness of ignorance.
