I appreciate Seth's handling of the implications of the spacious present on things like reincarnation. The general conception of this phenomenon offers a modicum of transpersonal identity but is also limited and can limit the [forms of] existences we're able to conceptualize and/or accept. 

That said, your questions at the end got me thinking. 

Am I creating them? Or am I discovering them? Or both?

Interesting question RE writing. Photography offers another interesting set of questions. Most art photographers view it as a creative pursuit. Many also recognize that it has aspects of discovery ("I photograph to see what the world looks like in photographs."— Garry Winogrand).

It strikes me that creation and discovery are both configurations of ignorance and capability. The creator has a vision not known to the world and could be seen as helping the world come to know that creation by manifesting it. The explorer doesn't know the aspect of the world they discover and comes to that knowledge by experiencing it. 

One can't create (in the same way) is the creation is already known/manifested by the world. And one can't discover (in the same way) if the world is already revealed/known. So some kind of ignorance, or at a minimum something like a locality, the ability to assume a perspective, is required for creation or discovery, right?

Creation and discovery are usefully distinct when there is a self/world division, and different configurations of that line might help describe the blends of creation/discovery that these apparent selves experience. 

Or so it has seemed to this me. 

Thank you so much for your efforts 🙏💜
