The image to your left is of the Ace of Cups in the Rider Waite Tarot Deck.
If you reflect on the symbolism you may observe that the cup or chalice is being held by a divine hand, usually representative of God or one of God’s angelic messengers. Above it is a dove, symbolic of the Spirit of God, holding a communion wafer marked with a cross. From the cup flows living water, symbolising eternal life.
This is the grail, the cup of Christ. What is offered here is the life of Christ, which is life without limit. These waters never run out.
