Dear Gabriel,
It is worth looking for a spiritual aspect even in non spiritual works. I was reading Tolkien’s The Two Towers for the upteenth time today. There is a lovely passage in the Window on the West when Frodo and Sam meet Faramir in Ithillen. Before they eat, the men of Gondor turn to the West.
We look towards Numenor that was, and beyond to Elvenhome that is and that which is beyond Elvenhome which will ever be.” Tolkien was religious but is careful to excise it from the ‘Lord of the Rings.’ But here is a passage that points to his belief in heaven.
