Answer:
It symbolizes his Pueblo traditions and hope for rain.
Step-by-step explanation:
The Man to Send Rain Clouds is a book written by Leslie Marmon Silko, an American writer who is also a Laguna Pueblo Indian woman.
This story is based on an incident Silko had heard about in her hometown - an old man had been found dead and given a traditional Indian burial, which angered a local Catholic priest, who wanted to officiate at the service. In her story, Silko shows the blending of traditional Indian and Catholic funeral rituals.
For Leon (a member of the Pueblo tribe) and his brother Teofilo, who buried the old man, holy water symbolizes their Pueblo traditions and hope for rain. Holy water was important for both Catholics and Indians.
