This quote by John Muir sheds light on a metaphysical question - is the universe, or god, or source consciousness infinite as many have claimed? Perhaps, but since source creates universes and realities with its imagination (yes, it creates everything via thought, intention, and imagination) and since imagination is inherently unlimited then what it can create and experience is indeed infinite.

That doesn't necessarily mean anything that it can imagine exists all at once right now. The space (an information space?) that holds it's creations may not be truly infinite but it can reuse that space by clearing parts of it and imagining new creations. The net effect is the possibility space of existence and experience is infinite.

So imagine wonderful!
