What was the specific 'wish [code]' that Sai had already fulfilled for Balasaheb Deo before the story about the Dnyaneshwari began?

The narrative in Chapter 41 introduces Balasaheb Deo's story by stating, "He fulfilled his wish [code] and gave him the addition of devotion." However, the provided passages do not go on to specify what this original wish was. The text uses this fulfilled wish as a prelude to introduce Deo as a devotee dear to Sai, but it immediately pivots to the central conflict of the story: Deo's subsequent struggle and resolution concerning the reading of the Dnyaneshwari. The details of that first fulfilled wish are not mentioned in this section.
