Nothing in the entire universe ever perishes, believe me, but things vary, and adopt a new form. The phrase being born is used for beginning to be something different from what one was before, while dying means ceasing to be the same. Though this thing may pass into that, and that into this, yet the sums of things remains unchanged.
OvidNothing retains its form; new shapes from old. Nature, the great inventor, ceaselessly contrives. In all creation, be assured, there is no death - no death, but only change and innovation; what we men call birth is but a different new beginning; death is but to cease to be the same. Perhaps this may have moved to that, and that to this, yet still the sum of things remains the same.
Ovid
