How does Hemadpant connect the necessity of having a Guru with the virtues of 'shraddha' and 'saburi'?

In Chapter 2, Hemadpant establishes a clear connection between the need for a Guru and the virtues of faith (Shraddha) and patience (Saburi). He argues that debating is a negative trait and that one should not compete with anyone. This humility opens the door to the core teaching that "Without a Guru, there is no knowledge or spiritual goal." Immediately following this, he states that "Without faith (Shraddha) and patience (Saburi), Not a bit of the spiritual goal is achieved." This juxtaposition suggests that these virtues are prerequisites for successfully following a Guru and absorbing their teachings to attain spiritual knowledge.
