Having a spiritual director is not a hard and fast rule, but the kind of discernment you will be doing with a community is similar to what a spiritual director will help you with. Learning about the person you are, your deepest desires, and your spiritual life in general can be extremely confusing, especially when left to your own thoughts. It is hard to know what is truly important, which thoughts are not as big a deal as you might make them, etc. Personally, my spiritual director is a crucial part of my discernment, the whole process would be so messy without a wise, holy priest to help me through. I can understand how hard it must be (we are very blessed to have many good, orthodox priests in the area, I know many diocese are lacking). Have you tried asking your priest if there is anyone he would recommend for you? Be honest, tell him you are looking for a spiritual director, you know he is busy, and you are not comfortable with some of your possible choices. I’m sure he will help if he can. Even if its someone a bit far away, meeting with them once a month or something would still be worthwhile. God bless you in your discernment, I’m sure the Lord will bring you where you need to be.
Also, to the above poster, the Nashville Dominicans are absolutely the best. Two wonderful parishioners I am good friends with have a daughter who recently made final vows. You are so right, fiercely orthodox, and so joyous! You can see in each of them that there is no place they’d rather be. God bless the work they do educating our youth
