Today I'll be praying the Luminous Mysteries. I've always liked the progression:
First Mystery is about baptism, a sacrament which is about the one person.
Second Mystery is about marriage, a sacrament that unites 2 people who will then procreate to be many.
Third Mystery is about community (the Kingdom).
Fourth Mystery brings in the supernatural world and our relationship to it.
Fifth Mystery goes one step further, is about the communion with our God.
