The Rosary?

In the past I have used a Rosary to pray and meditate. Of late I have not used one for some reason. I am thinking I would like to meditate with one again but I'm not sure if it's "allowed" or not. My rebellious streak says, "Of course you can do it! Who has the right to tell you not to?" While at the same time I have the idea that maybe I ought to ask the Pastor if it's a good thing or not.
I did find a
"Lutheran Rosary" on line. As far as I can tell there is no direct heresy there, although the one place where it seems to address the Virgin Mary makes me a bit uncomfortable, even though that is attributed to Martin Luther!
I guess what I'll do is check it out with the Pastor after all.
