According to Chapter 6, how does devotion to a Sadguru like Sai Baba lead to spiritual realization and the attainment of life's goals?

Chapter 6 explains that devotion to a Sadguru is the key to both spiritual realization and worldly fulfillment. The chapter describes how the Sadguru awakens the inherent sense of 'I am He' (Soham) within a devotee, dissolving the egoistic sense of 'me and mine' and revealing the harmony of non-duality (Advaita). This leads to a state of supreme bliss. On a more worldly level, the text makes a significant promise. It states that by surrendering completely with body, speech, and mind to the capable Sai, a devotee will find that the four primary goals of human life—Dharma (righteousness), Artha (wealth), Kama (desire), and Moksha (liberation)—come to hand naturally, without even having to ask for them.
