Wanderers have to polarize?

[Lighthead]

Does anybody know where it says that Wanderers absolutely have to polarize to leave 3D in the Law of One material? I probably have already asked this before, but I'm too lazy to look at my old threads or anywhere else. I don't really remember Ra saying that in exact terms. If it exists, I'm assuming that it could be under Harvest in the lawofone.info site. I'll try to look it up too. Thanks.

If I am correct, I don't think Ra ever says something directly to this effect. I think it is commonly inferred.

Q'uo does say this though. 

Thanks. No wonder there's so much debate over it.

Hmm... I'm not so convinced on Q'uo...
