Ethereal
[adjective] referring to that which is beyond earthly; extremely delicate, heavenly or dreamlike. Impalpable. How we viewed and imagined the world as children after delving into books, films, and the like, consisting of wonder. Almost unattainable, unless you look a little harder, think a little less, and feel a little more.
While it infers otherworldliness lies beyond the skies, I’d like to suggest such beauty and unearthliness can also be found amidst the verdancy beneath your feet.
etymology: Greek aither - ether, the divine, otherworldly air breathed by the gods.
