I remember reading Autobiography of a Yogi where Yogananda depicts crying as a child because he was stuck in this tiny body that wouldn't do what he wanted it to do.
I read it too.
And, the key point there is that one is IN A TINY BODY THAT WON'T DO WHAT YOU WANT IT TO DO. THAT is the context of the "thetan". And, nobody is going to change that very defining context.
THAT is the relevant context. THAT is why one is understanding of a child, and treats them with great patience.
My daughter had a baby girl last year and it has been fascinating watching her develop, make connections, and slowly and gradually figure out the world around her. She has her own things to deal with because of that small body. She is learning how to control her muscles. She is learning how to walk (just recently). The IDEA of being a "little thetan" is entirely meaningless to me regarding her. I simply love her, treat her with total patience, NEVER get angry, never raise my voice around her, and on and on and on. My daughter treats her the same way. Any idea of "oh, she is a big thetan" adds NOTHING here. I find it quite irrelevant. She gets frustrated at times, but that is the nature of growing up.
A better understanding to concentrate on is that "thetans" respond FAR BETTER to love, patience and understanding than they do to Scientology idiocy like "you better make it go right you asshole". THAT is what happens when one treats a "thetan" like a BIG BEING in a little body. Total lunacy.
A "spiritual being" in a small and growing body has its OWN UNIQUE problems and difficulties. THAT is what one should focus on. Focusing on some IDEA that he or she is really some BIG THETAN who SHOULDN'T ACT THEIR AGE is pure idiocy.
I am not saying that you disagree, and I am only pointing this out.
