According to the text, what is the relationship between surrendering one's 'I-ness' and achieving happiness?

Chapter 2 draws a direct and powerful link between surrendering ego and finding joy. The author states that "Surrendering the 'I-ness' at His feet brings immeasurable happiness." This concept is further emphasized with the line, "When ego goes, the whole world becomes full of happiness." The text posits that the sense of being an individual agent, the feeling of 'I speak' or 'I do,' is a barrier to true contentment. The path to bliss, therefore, is to recognize a higher power as the true doer—in this case, Sai Baba as the "puppeteer"—and relinquish the false notion of individual authorship and action.
