" Part of himself held back and would not allow him to commit to the dwarf gods and bind his identity and his sense of well-being to something he did not understand. He also had difficulty accepting that if gods did exist, the dwarf gods were the only ones. Eragon was certain that if he asked Nar Garzhvog or a member of the nomad tribes, or even the black priests of Helgrind, if their gods were real, they would uphold the supremacy of their deities just as vigorously as Glûmra would uphold hers. "How am I supposed to know which religion is the true religion? he wondered. Just because someone follows a certain faith does not necessarily mean it is the right path. . . . Perhaps no one religion contains all of the truth of the world. Perhaps every religion contains fragments of the truth and it is our responsibility to identify those fragments and piece them together. Or perhaps the elves are right and there are no gods. But how can I know for sure? "
