Who is the type of devotee that Sai Baba promises to give His full assistance to and even serve in their home?

In chapter 2, Sai Baba specifies the qualities of a devotee to whom He provides complete support. He states, "He should dissolve his ego and surrender it at my feet. To one who acts thus in life, I give full assistance." Sai Baba elevates this promise by declaring that He will not only help with the story but will "serve in all ways in his home." This supreme assistance is reserved for the devotee who successfully eliminates their ego, allowing Sai Baba to enter with 'I-ness' and accomplish the work through them.
