What can we learn from the story of Boss Dharamsee about the proper attitude when approaching a Guru?

The account of Boss Dharamsee in Chapter 35 teaches that approaching a Guru with ego and skepticism, or 'clinical scrutiny', can be a barrier to spiritual experience. Dharamsee was initially troubled, questioning why Baba would force upon him grapes he disliked. His breakthrough came only when he surrendered his judgment and obeyed Baba's command to 'Throw them in and eat.' It was in this moment of obedience that the miracle occurred, the grapes turning seedless. As the chapter explains, this experience caused 'all his ego [to drop] away, and love for the saint was born.' The story illustrates that becoming egoless and surrendering at the Guru's feet is the key to enjoying the 'festival of happiness' and receiving grace.
