I think maybe he means it isn't his mind/ego/personality. Most people think they are their mind, coupled with their body. Some just think they are their body. It's true that a higher power works through us and that we are an extension of that higher power, but we have a mortal mind that imagines it's the boss. It isn't. It can pretend to be, though, and usually does just that. Its knowledge and its grasp are very limited, though quite complex. It could not even function were it not supported at all times by the divine mind which is coursing through it and giving it power, form, and function.

That is why God is spoken of as the Father or the Mother in various religious traditions. Divine mind is the origin of the mortal mind and being. It is beyond time or space, but creates both of them. It creates every atom and waveform. Its purpose can be speculated about, but is unknowable from the perspective of limitation. We are all accustomed with limitation and work within it in order to perceive things as "separate". Things appear separate to us, but are all existing as One Unity. The One Unity manifests as trillions of apparently separate things, energies, events...from atoms to galaxies...casting itself upon a created field of space and time, like a movie on a screen.

The Earth Scientist is like a busy little semi-intelligent worm in a garden in a tiny subplot of that movie, climbing slowly up a blade of grass, and describing everything he sees around him with all the detailed observation and measurement he can muster and all the tools at his command. This worm thinks he is alone, but he is not. He has no idea that there might be a gardener who created the garden he inhabits...or an even larger World within which the gardener is as relatively limited as the worm. This little worm may be able to mightily impress other worms in his garden, and not surprisingly, because he knows a bit more about the blades of grass than they do, and he is familiar with professional jargon which leaves them feeling at a bit of a loss.

Very impressive. Like Owl in the Winnie-the-Pooh books, the scientist worm knows big words.

One day he will realize that he has become more than a worm, and the big words will be seen as a child's game. For many, this does not happen until they die. But they do not really die. They just leave the body behind.
