Answer:
What loses its head in the morning but gets it back at night?
I am gentle enough to soothe your skin, light enough to fly in the sky, strong enough to crack rocks. What am I?
Born of sorrow, grow with age, you need a lot of me to be a sage. What am I?
By Moon or by Sun I shall be found. Yet I am undone if there's no light around.

Though not a plant, has leaves. Though not a beast, has spine. Though many wouldn't need this thing, It's more valuable than wine.
