Based on Chapter 6, why is having a Sadguru considered so essential for navigating life?

Chapter 6 emphasizes the critical role of a Sadguru by using a powerful analogy. It states that whether in spiritual or worldly matters, a person's life is like a boat, and the Sadguru is the helmsman. Only the boat with a Sadguru at the helm is assured of reaching the 'far shore,' or its ultimate destination. This chapter further explains the profound benefits of complete surrender. By surrendering with body, speech, and mind to a capable Sadguru like Sai, a devotee can naturally attain the four primary goals of human life—Dharma (righteousness), Artha (wealth), Kama (desire), and Moksha (liberation)—without even having to ask for them.
