According to the text, what are the fundamental questions a person must explore to achieve the 'true success of birth'?

Chapter 8 of the Sai Satcharitra identifies the 'true success of birth' as the realization of the Eternal, which is achieved through deep self-inquiry. The text explicitly lays out the core questions one must investigate to find this success. As written in Chapter 8, these pivotal questions are: "Where have we come from? Who are we? What is the reason for human birth?" The author suggests that a person who knows the "seed," or the answer to these questions, is truly proficient, and that without this knowledge, life is merely a state of exhaustion. This highlights the importance of spiritual contemplation for a meaningful existence.
