Bit - how awesome is that?
I have sycamore seed-balls at home and work. My grandfather used to write me letters on sycamore bark and sign them "A. Troll" or "D. Troll" and tell me that he "found" them.
There is a young sycamore tree at my work, and there were a few times I went out there and hung out next to it, and the trunk was covered in flies and the leaves were wilty. I was out there to meditate, so I suggested to the tree that we ground and center together. I held onto one of its leaves, and imagined both of use extending our roots down toward the center of the earth and bringing up that earth energy together. What surprised me, is that it seemed to me that the tree had an easier time with this than I did, and that the energy not only came up through it faster but that it sort of spilled over onto me. Since then, when I can, I go out there and listen to podcasts or meditate or check bfp under the tree on my breaks, and I always tell the tree hi and often sit in the grass and lean against the trunk. No more flies, btw.
