In what ways is the Sadguru portrayed as the ultimate means to salvation in the tenth chapter?

The tenth chapter of the Shri Sai Satcharitra portrays the Sadguru as the supreme path to salvation, requiring no complex rituals or intellectual struggles. The text states that simply remembering the Guru with love can untie the knot of birth and death, describing this as the best sadhana, costing nothing. It emphasizes that where the service of the Sadguru is pure, worldly existence is completely destroyed. Unlike trusting a normal boatman to cross a river, Chapter 10 posits that one must trust the great Guru to cross the entire ocean of existence, as he alone can grant liberation and break the knots of the heart.
