How did Sai Baba counter Dev's feeling of being deceived, and who did Baba say was really at fault?

Sai Baba countered Dev's accusation of deceit by shifting the focus from His promise to Dev's perception. When Jog related Dev's feelings, Baba explained that the failure was not His. As Chapter 40 recounts, Baba instructed Jog to ask Dev, "You did not recognize Me! Why then did you call Me?" He then detailed how He fulfilled his promise precisely: He came with two others for the meal, just as he said he would, in the form of a Sanyasi and his companions. By doing this, Baba demonstrated that his word was perfectly kept. The fault, therefore, lay with Dev, whose worldly expectations and lack of spiritual insight blinded him to Baba's presence.
