How does Chapter 6 describe the power and grace of a Sadguru, specifically referencing Sai Baba?

According to Chapter 6 of the Sai Satcharitra, the power and grace of a Sadguru like Sai Baba are immense and transformative. The chapter begins by likening the Sadguru to a helmsman who safely guides the boat of life to the "far shore," whether in spiritual or worldly matters. The text emphasizes the profound effect of the Sadguru's touch, stating that when Sai Baba places His hand on a devotee's head, it can burn away the ego, which is described as the subtle body. This blessing, often accompanied by Udi from the Dhuni, washes away the accumulated impurities of many births, making the devotees pure and filling their hearts with self-bliss and love.
