Why was the wealthy merchant Ratanji so unhappy, and what guidance did he receive to solve his problem?

Despite his wealth, the merchant Ratanji was deeply unhappy and constantly worried because he had twelve daughters but no son to carry on his lineage. According to Chapter 14, this sorrow made his food and drink taste bitter and left his mind without peace. He considered it a 'stain' he pleaded with God to wash away. He confided in Das Ganu, who had great faith in Sai Baba. Ganu advised him, 'Go to Shirdi; you will obtain your heart's desire.' He instructed Ratanji to take Baba's darshan, surrender to Him completely, and explain his troubles, assuring him that Baba's 'inconceivable handiwork' would lead to fulfillment.
