6D Wanderers: 3D Lessons?

[Wander-Man]

Okay, I'm on lunch so I didn't have a chance to read this entire library of posts in this thread, but I'll just address something really quickly to unity100

in descriptions and harvests of 3, 4 and 5d, in Ra material, we learn that the harvest of 3d is the only one requiring polarization...it doesnt matter how much you are polarized. that means that, entities manifest in the understanding of green ray in 4d, and the activity of understanding becomes one of learning the dance of existence in 5d. and in 6d, as Ra tells us, polarity becomes a thing of the past.

52.9 Questioner: I would just include the question as to why the time of harvest is selected by so many Wanderers as time for incarnation?
Ra: I am Ra. There are several reasons for incarnation during harvest. They may be divided by the terms self and other-self.

The overriding reason for the offering of these Brothers and Sisters of Sorrow in incarnative states is the possibility of aiding other-selves by the lightening of the planetary consciousness distortions and the probability of offering catalyst to other-selves which will increase the harvest.

There are two other reasons for choosing this service which have to do with the self.

The Wanderer, if it remembers and dedicates itself to service, will polarize much more rapidly than is possible in the far more etiolated realms of higher density catalyst.

The final reason is within the mind/body/spirit totality or the social memory complex totality which may judge that an entity or members of a societal entity can make use of third-density catalyst to recapitulate a learning/teaching which is adjudged to be less than perfect. This especially applies to those entering into and proceeding through sixth-density wherein the balance between compassion and wisdom is perfected.

Why would a 4 5 or 6D Wanderer want to polarize so badly that he would risk getting caught up in a couple 3d cycles, if polarization does not matter?
