What was the significance of the green kafni that Kashiram provided for Maharaj, which became his standard attire?

There is a slight inaccuracy in the premise of this question. While Kashiram's devotion was immense, the green kafni he provided did not become Maharaj's standard attire. Chapter 0 clarifies that Kashiram did indeed stitch and give Maharaj a green kafni and a green cap. However, the text explicitly states that Maharaj usually wore a white kafni and tied a dhoti on his head. Kashiram's service was extensive, also including a vow to provide chillum, tobacco, and firewood, but the green clothing was an offering, not his regular dress.
