The Rosary is a private devotion. There are no rules.
In prayer we seek to make our prayer life more devout as our journey into faith continues.
What is the definition of devout? To me that is a person such as yourself who has concerns for his or her prayer life and how to enrich it.
What does devout look like.
It can look like a monk praying as he goes about his chores, It can mean a monk spending 6 hours praying on a marble floor mid winter in bare feet and hardly any winter weight clothing.
It can look like a mother in childbirth who is praying for a safe delivery in between a few choice words to her husband for getting her into the predicament of giving birth, one she has no control over her body, and telling nurses to stop doing x y or z because it is annoying or painful
When I pray the rosary, I usually think of one thing and continue to come back to that one thing, and only that. So I pray and visualise or think of that one thing.
I pray walking, in bed, around the house, cleaning those distasteful areas, driving, in public with others,
I don’t try to get really anything out of it or put anything into it. I just pray and think of my favourite mystery.
There are three types of prayer, vocal, which is the Rosary, meditative, which can also be the Rosary but can also be reading the Bible verse or chapter, then sitting quietly and thinking about it, and then there is contemplative prayer.
What is your personal prayer style, initially if you want to meditate on each mystery, it is hard going, learn to pray the Rosary first, then introduce the various mysteries as more then passing thoughts.
As to what is devout, you can have three people, a very holy monk living in a cave in the times of the early fathers of the church, a martyr who would choose death over worshipping pagan idols, and a mother of 8 or has very little time to do much other then passing quickly through personal prayers while her families needs are met.
There are some who pray " Lord Jesus, have mercy on me, a sinner’ as their prayer and prayer alone and are very devout.
