The Satcharitra mentions Sai Baba's relationship with men and women. Did he ever specifically refer to anyone like Gajanan Maharaj as his brother?

According to Chapter 37 of the Shri Sai Satcharitra, Sai Baba's general disposition was one of universal kinship, as it states, "He holds brotherhood with men and treats women as His sisters or mothers." This was a broad principle he applied to all. However, the provided text for this chapter does not contain any specific mention of him referring to Gajanan Maharaj or any other particular individual by name as his brother after their passing. The description suggests a spiritual brotherhood with all of humanity rather than a specific familial-like bond with certain people.
