We change Spiritually just as we change Physically over a life-time.
Perhaps the major difference is that Spiritual growth can stop,
whereas Physical change is continuous process
followed by decay and eventual death.

The Spiritual journey can be seen through a number of mirrors.
From the image of the eggs progress to a butterfly
to more rigorous descriptions.

Perhaps the fullest realisation is
that is never complete in this life
and another is yet to be fully verified.
