The tree as shelter; the branches of the tree weep down instead of rising up, reaching down to the water, down to the ground. You can pass through into this sheltered space, behind the green curtain. Then you feel like you are in a room enclosed but not entrapped. The veil of leaves is dense enough to create a sense of envelopment and broken enough for you to remain aware of what is happening outside. The human sense of, or need for safeness must be primal and that sense is triggered in this space.
The tree as shelter— nature as sheltering, providing and also indifferent, magnificent. It is more complex than simply a roof.
