Here's why the author, Rudolfo Anaya, uses this imagery:
* Contrast with reality: Anaya's novel is set in a time of poverty and hardship, particularly for Mexican-Americans in the Southwest. The "milk and honey" imagery creates a stark contrast between the biblical ideal of a flourishing land and the harsh realities of Antonio's world.
* Connection to ancestral heritage: The image of the Promised Land also evokes a connection to Antonio's ancestral heritage. As a Mexican-American, Antonio's family carries the weight of their history and the displacement and hardships they have faced. The "milk and honey" imagery hints at the hope for a better future, a place where they can find peace and prosperity.
* Symbol of spiritual yearning: For Antonio, the land becomes a symbol of something more than just physical abundance. It represents a spiritual yearning for a place of belonging, acceptance, and peace, a place where his soul can find nourishment and solace.
Overall: The use of "milk and honey" in *Bless Me, Ultima* is a complex and evocative image that reflects the complexities of Antonio's world and the multifaceted nature of his journey towards self-discovery. It speaks to the hopes and aspirations of his family and the enduring spirit of his heritage.
