William Shakespeare

"All the worlds a stage, and all the men and women are merely players. They have their exits and their entrances; and one man in his time plays many parts, his acts being of seven ages." 

In short you are nothing but, energy choosing experience yourself outside of yourself to exit and enter for the soul purpose of helping and healing humanity. This process, goes on, and on. It's continuous these are the essential workers... they are absolutely what this planet needs. Previous trips we learned previous lessons; making us best fit in some places to create positive changes amongst the way.
