American poet e.e. cummings wrote this, apparently on Easter Sunday. He continues: "(I who have died am alive again today, and this is the sun’s birthday; this is the birthday of life and of love and wings."
Associating rebirth with cycles in nature isn't just a Christian or even religious thing. In temperate climates, especially, every year life that seems to die in autumn is resurrected in spring. Even where trees don't drop their leaves and the earth doesn't sleep under a blanket of snow, subtle changes may indicate a slowing, a retreat, a sense of suspended animation. And now, in the spring, as sap begins to flow, buds begins to form and shoots begin to sprout, life is resurrected. Animals emerge from hibernation, like Sleeping Beauty woken from her death-like 100-year sleep.
