Praying faster than the speed of light

A question for those who've read Paul Miller's A Praying Life:

How do you linger over a prayer card (I don't know any Ernies, this is a sample card) for only a few seconds? What exactly does that kind of prayer look like?

I love the idea of prayer cards, and am building my stack of them. But I can't figure out how Miller spends only a few seconds on one and prays meaningfully.

Let me know what you think...
