Escalators are wonderful things. I like the flat ones you can walk up better than the moving stairways. Part of the pleasure is, of course, that you just stand on them and they do all the work, while, if you do choose to walk you get twice the speed for the same amount of energy.
I was on one this afternoon and feeling energetic I started walking up, and as that special 'why-can't-life-be-like-this-all-the-time' feeling came over me, I suddenly found myself wondering about, of all things, my daily Rosary.
I think it must have been that thought about saving energy on the escalator which somehow led me to the make a connection with saving time on the Rosary.
The Rosary is meant to be, and can be, a deeply contemplative prayer which invites our complete attention, all our 'prayerfulness'.
We may say the Rosary while out walking but it is not a good idea to go for a walk to say the Rosary, at least, that's what I've found.
There are so many things to dissipate our attentiveness during a walk that our prayer inevitably suffers. I can't read a book and listen to music at the same time - one of them eventually becomes 'background noise' but then, your experience may be different.
