Why does the author cite the examples of Rama and Krishna before introducing the importance of Shraddha and Saburi?

In chapter 2, the author mentions that even divine figures required a Guru—Rama held the feet of Vasistha, and Krishna gathered wood for his Guru Sandipani. These examples serve to dismantle the author's own pride and his tendency to debate, making him question, "Then what of me? Why should I debate?" This lesson in humility directly precedes the crucial teaching that "Without faith (Shraddha) and patience (Saburi), not a bit of the spiritual goal is achieved." The sequence implies that true faith and patience can only arise after one has humbled the ego, just as even the greatest incarnations showed humility and submitted to a Guru.
