What does Chapter 6 of the Sai Satcharitra say about the power and importance of a Sadguru?

Chapter 6 of the Sai Satcharitra profoundly emphasizes the glory and essential role of the Sadguru, stating that whether for spiritual or worldly affairs, a boat with the Sadguru as its helmsman is the only one that will reach the far shore. The text describes the immediate and powerful effect of the Guru, noting that the mere mention of 'Sadguru' brings Sai Baba to mind, who then places His blessing hand on the devotee's head. As this chapter explains, this divine touch, combined with Udi, is so potent that it can burn away the ego, which even the fire of dissolution cannot, and fills the heart with immense bliss and love.
