The book Sam looks through at around 32:37 seems to be the Aunt Morgana's "recipe book" from Elvira: Mistress of the Dark (1988). The last page Sam sees is entitled "Adraka Kozorol"; this is the recipe Elvira makes for a picnic. She even wonders where Aunt Morgana kept the edrazeba.
In addition to the religious overtone of Sam's opponent in this leap, there is a religious undertone on Sam's side as well. The name of the man Sam leaps into is Joshua Rey. Joshua is the Hebrew form of Jesus and Rey means King in Spanish, so his name means "Jesus the king."
