What were the contents of the letter Dev wrote to Jog after the Udyapan ceremony?

After the Udyapan was finished, Dev wrote a letter to Jog expressing his deep confusion and disappointment. In the letter described in Chapter 40, he asked how Baba could have deceived him and wondered why Baba's promise to attend had failed. Dev lamented that he had waited with great effort but received no clear experience or proof of Baba's presence. He expressed his bewilderment, stating, "I don't understand this at all," as he grappled with the feeling that Baba's assurance to him had turned out to be false.
