We are meant to be tested. It is not our job to be protected from trials and tribulations. No, we are to be tested over and over again because it is the only way that we understand the celestial stuff we are made of, character and heart.
With this line of thinking it follows that our goal in life if we are smart and lucky enough to be taught is to be undefended, completely.
In this fluid state we are open to all that life has to offer and it has a lot to give. We are taught to be careful to be lean mean fighting machines. Yet I think as a culture we have taken this too far. We are always defending against being hurt or embarrassed yet it is in those moments that we are most alive and we don't die. Not really, I mean of course metaphorically. No one can hurt us except our thinking our idea's about someone or something. It is all in our power...only everything.
We are celestial Angels/beings made from the same stuff as the stars in the galaxies. Welcome the tough times and be sweet as you navigate them and continually ask yourself "Am I soft, am I open?" life is difficult and we may be destroyed (so our story goes) ask yourself "am I still open soft and willing in the face of deep adversity"?
You say "but people hurt others and lie and do horrendous things"...They do and still we must find a way to be fluid and like water flow and like water remain strong yet flexible.
I believe it is the fountain of youth.
