Based on the teachings in Chapter 6, what is the significance of a Sadguru in a person's life, both spiritually and worldly?

According to Chapter 6 of the Sai Satcharitra, the Sadguru is of paramount importance in both spiritual and worldly affairs. The text likens the Sadguru to a helmsman, stating that only the boat guided by him can safely reach the far shore. This chapter emphasizes the transformative power of the Guru's blessing hand, which, when placed on a devotee's head, can burn away the subtle body of ego—something even the fire of dissolution cannot do. The Guru's presence grants stability to a wandering mind, washes away accumulated impurities from many births, and ultimately helps the devotee achieve a state of self-bliss. By surrendering to a capable Sadguru like Sai, the text suggests that all four life goals—Dharma, Artha, Kama, and Moksha—can be attained effortlessly.
