I submit that it simply changes such as the catepiller changes from larvae to cocoon, to butterfly... one phase, one form to the next.
When we "end" this form, we move onto the next. We begin as "larvae" and with the proper set of circumstances move to our "cocoon" and then to "life", and then to the next phase. Each phase "ends, yet the entity does not.
Just my thoughts.
