- a Christian symbol, a mythological goblet with the blood of Jesus Christ.
- appears quite rarely in dreams since high moral purity must be maintained to see it – a purity in which we do not at all waver from the highest spiritual ideals of Christianity.

- the brave knight's quest for the holy grail: an allegory of the inner spiritual journey.
