Wicca is not a passive religion. If you prefer to have somebody preach a sermon and tell you how to think, then it's certainly not the religion for you.
I have genuinely had people in the past come to me with concern about the Esbat. They had stood in the circle and gone through the motions. They had watched me Draw Down the Moon. But then what?
I was the High Priestess, but I didn't tell them what to do. I was the representative of the Goddess, but I didn't direct them in a round of thou shalt and thou shalt nots.
It was about this time that I realized that I'd failed in my duties as High Priestess. Not because I hadn't transformed into anything more divine than usual, but because they had entered the circle unable to grasp what it was all about. Oops.
That was one Esbat circle when I really would have been better to have recited that old stand-by, The Charge of the Goddess. Doreen explained the entire Wiccan faith and practice so brilliantly there, that my confused wards would have been in no doubt as to what was going on.
The role of the High Priestess, in Drawing Down the Moon, is akin to that of a lightning rod. The energy is up there and potent. We just need to direct it into our circles. What we do next is precisely the same dilemma posed by house-holders, whose home has just been hooked up to the mains.
The answer - whatever you want! Whatever you have to plug into it, go, go, go! Obviously within reason and subject to certain health and safety lores, like Do As Thou Wilt An It Harm None.
So how should you approach an Esbat? Whether in a coven or as a solitary, the answer is the same. You bring to the ritual all that you've been working towards. You use that moment of high energy to infuse your project with purpose, or to ask the big question and seek clarity within your own mind.
No High Priestess is going to do that for you; nor a High Priest either. And certainly not the Mother Goddess!
