Carmel IS Marian in focus. . . so, as was said, there should be no inherent conflict. We should remember the role of Our Lady of Mount Carmel in the development of the Order and that Marian devotion is one of the building blocks of our way of life, along with daily Mass, LOTH, spiritual reading and mental prayer.
However, Fr. Deeney (head of OCDS) has pointed out one way there “could” be a problem. This would be in cases where the Marian focus dwarfs the Carmelite. For example, if the individual felt little need to learn and absorb the writings of the Carmelite Saints prefering instead to exclusively follow non-Carmelite teaching, spent all their time in community discussing things like Fatima and other apparitions, or felt little need for mental prayer thinking the rosary has that covered. Father’s point in these types of comments isn’t that the Marian focus is bad; rather the emphasis is skewed in a way that isn’t necessarily Carmelite. It “could” call into question the validity of one’s vocation and that maybe there might be better places in the Church for this type of individual.
My guess, though, is that these type of comments probably don’t apply to you. And, if you’re just starting out in Carmel, remember discernment in these matters is a very long process so you have plenty of time to think and pray on the matter. In the short run though, it would probably be best to discuss this directly with your formation director. Hopefully he/she can dispel your concerns in short order.
Hope this helps,
PS: A good Carmelite is to *follow Mary’s example *to always ponder Him in our hearts . . .
