Yes, you talk to your director! Each day your director suggests a passage of Scripture for you to reflect on, and then the next day you talk it over with her or him. A few sentences can lead you on countless winding paths and even, sometimes, to a genuine inner stillness and alertness to the Spirit of God.
No, you don't have to do another single thing. One of my friends asked about the work of preparing meals together -- nope. The delicious meals were prepared and beautifully presented by the kitchen staff -- which also works in silence, so as not to disturb the retreatants in the dining room.
I thought longingly of my computer and its internet access maybe three times in eight days.
I found the silence easy and the eight days short. I'm sure one's mileage varies, and I wouldn't predict even my own future experience based upon this recent one. But I have a pretty well-established practice of lengthy daily silence for listening for God, which itself has an effect on the prayer going on inside my head or through my activities even when I am chattering away or otherwise engaged during the rest of the day. So, this time at least, the silence went well for me.
I'll try to write a little about spiritual direction tomorrow. It's been such a significant part of my life for the past two years that I tend to forget how weird the entire concept sounds. But yes, I am aware that when you use words like "spirituality" or "direction" in most of the contexts I inhabit, people start thinking New Age or Eastern tradition or medieval or rigidity of discipline.
For now let's just leave it at this: you will never have to worry about mistaking me for Mother Teresa.
Enjoy the sunrise!
