Transformation always seems to take place in darkness.
In order for a caterpillar to become a butterfly, it first must spend a period of time in darkness, hanging upside down in a cocoon. It's there that it sheds what it once was, before emerging with wings and colour and as a far more beautiful final product.
If it didn't enter the darkness, it couldn't emerge as it does.
Don't assume the darkness is the end result.
It's often the location where we shed everything we don't want to be, in order to become what we could be.
