Why did Das Ganu instruct Ratanji to seek a blessing from Gajanan Maharaj to obtain a son?

There seems to be a confusion of names, as the text from Chapter 14 does not state that Das Ganu mentioned Gajanan Maharaj. In fact, the passage explicitly says that when Ratanji revealed his sorrow, 'Ganu said, "Go to Shirdi; you will obtain your heart's desire."' He specifically directed Ratanji to take Sai Baba's darshan, bow at his feet, and tell him the secret of his heart. The entire guidance provided by Das Ganu was focused on seeking the grace of Sai Baba of Shirdi, and Gajanan Maharaj is not part of this narrative.
