"Slowly Rising" suggested to me the image of the sun.
A seed was born beneath the sun, the source of all existence.
The seed absorbed the light. It created more seeds like itself, gradually increasing in number.
Time passed, but still their numbers slowly continued to rise,
and before long they were quietly swallowed up by their own shadows.
After everything that had lived had perished, nothing but an empty world remained.
There, once again, an environment where the next living things could grow silently began to spread.
