I say a rosary almost every day, but sometimes more automatically than thoughtfully. The mysteries can provide points for reflection or focus of intention (praying especially to the Holy Spirit during the decade devoted to Pentecost, for example) when I pay attention.
The sorrowful mysteries are traditionally recited on Tuesdays and Fridays. Last week I stumbled across a reflection by Erin about the Agony in the Garden. She wondered how our all-knowing, all-powerful God could experience fear, especially with the intensity described in Scripture. Her thoughtful response (I won't call it the answer, because, really, who knows?) was amazing--you should really go read it now!
Meanwhile, I've been praying for so many intentions lately: an uncle with cancer, a cousin who needs a transplant, a family with major difficulties, a friend of a friend having cancer surgery, and on and on. Today will be another candle-lighting day (We burn one on the island as a reminder--see flame, say a prayer.).
