How does Chapter 2 connect the necessity of Shraddha and Saburi to the historical context of the 'Yavana' armies mentioned in the text?

Based on the provided excerpts from Chapter 2, there is no direct connection made between the principles of faith (Shraddha) and patience (Saburi) and the historical references to the 'Yavana' armies. The chapter mentions the 'Yavana' (Muslim) armies in a section discussing the historical context of the original statesman Hemadpant, after whom the author was named. The teaching on Shraddha and Saburi appears later in a different context, where the author reflects on the importance of having a Guru and the futility of debate for spiritual attainment. The two topics are not linked in the source material.
