Let me tell you something wonderful and strange.
When I'm in a place of many pagans—in the midst of a ritual, or at a summer festival, say—I not infrequently smell the smell of sweetgrass, even when none is burning.
This is what sacred smells like.
And not just when I'm among pagans, of course. I can be walking down the street, or by the River, or in the woods, and suddenly, there it will be: that unmistakable, woodruff-y fragrance, even where no sweetgrass burns, where no sweetgrass grows.
What atomized nano-particles are these, wafting on the air, that my mind somehow reads as sweetgrass where no sweetgrass is? Whoever may know, ye wise, O let you tell me.
But well I remember the old saying concerning Mabh, our beloved Earth: Her hair smells of sweetgrass.
The “odor of sanctity”: this is what sacred smells like.
