A parrot can copy or mimic what a human being has said.
Our job is not to ‘parrot’ what another human has said, but to create our own original series of words, particular for our life.
It is our design.
A spell is simply a carefully chosen series of words, said with intent. This is exactly what: our language ability can also create for our life.
As humans we are our language, and it is why we have the size brain we do.
Being prevented from speech enabled me much insight of when it was absolutely necessary, when it was adverse to do, and of the whole point of it! : )
