The Social Lives of Trees

[Steppingfeet]

But whereas the tree-people were very much a product of their past, finding it impossible even to fight, the exercise of free will on this planet (?) can completely obviate the biases of their past evolution. I don't fully understand this.

For what it's worth, I would zoom out.  First, moving from one density to the next is going to open up a world of new choices as well as many new categories of choices.  So, the country bumpkin just coming in from 2D is going to face a bewildering array of ways of doing things, and it will be no great surprise when they begin to explore new cuisines, new mating patterns, new kinds of pop music, pornography and illicit drugs.  Are we not all things?  (Yeah, it's a big old mess, but don't blame me.  This one is not my fault.)

I agree completely that said country (or urban) bumpkin fresh in from 2D will "face a bewildering array of ways of doing things." (Ra describes catalyst for the early third-density entity as falling into patterns that are "random." As the entity biases its consciousness toward one polarity or another, those patterns will be more intelligently designed in accordance with our free will to facilitate our chosen polarity - In other words, increasingly less random.)

But I think what you're saying misses the point I was driving at. You seem to be saying that the new 3D entity has the total freedom to explore (or be confused by) the wide array of choices. Yet, Ra speaks of the entities that evolved from trees as not having that full menu of choices available to them, or at least not being able to explore through their own actions that full menu. Instead, the former tree entities are limited or constrained by their past: they seem practically incapable of experiencing and expressing bellicosity; so much so that they need to mine the memory of a poor third-density fellow just to get the taste of it.
