It’s called Pray as You Go and it is produced by the British Jesuits. Here is the blurb from their website.
Pray-as-you-go is a daily prayer session, designed for use on portable MP3 players, to help you pray whilst travelling to and from work, study, etc.
You can download the files in a variety of audio formats. Check it out and use if it is difficult for you to find time to pray. I’ll also include it as part of the links you’ll find here on this blog so that if you forget the site and want to visit it, you can. Ain’t I just swell? 🙂
