What happens to Wanderers after Harvest?

[Ankh]

I have long been pondering this. If a Wanderer incarnates into 3D, it does so to help assist the planetary vibration, to be itself as best as it can and simply learn to love, correct? Does then the Wanderer need to re-choose how it shall polarize, and if so, does its choice and life experience determine where the entity will go after Harvest?

Are Wanderers present here going to graduate to and go through the 4D experience in addition to this 3D experience or will they, regardless of choice to polarize, and whether they have remembered or not, return to the respective density they had come from either at Harvest or at the end of their 3D incarnation? Let's say a Wanderer doesn't incur any sort of karma in this lifetime (or at the very least, clears it up and leads a humble life), will it be subject to 4D+ graduation? Can it be possible for a Wanderer to have to repeat 3D all over again?

Where do Wanderers go once Harvest comes?

My current understanding of the Ra material is that Wanderers go home, to their home vibration, unless some sort of karma hasn't occured or Wanderer change the polarity.

Here Ra says that they go to their home vibration:

Questioner: I think that to clear up this point I will ask a few questions that are related that will possibly help me to understand this better because I am really confused about this and I think it is a very important point in understanding the creation and the Creator in general, you might say. If a Wanderer of fourth, fifth, or sixth-density dies from this third-density state in which we presently find ourselves, does he then find himself in the third-density time/space after death?

Ra: I am Ra. This will depend upon the plan which has been approved by the Council of Nine. Some Wanderers offer themselves for but one incarnation while others offer themselves for varying lengths of your time up to and including the last two cycles of 25,000 years. If the agreed-upon mission is complete the Wanderer’s mind/body/spirit complex will go to the home vibration.

And here Ra says that it's the spirit complex which moves along the line of light upon Harvest:

The spirit complex of each harvested entity moves along the line of light until the light grows too glaring, at which time the entity stops.

And since it is the spirit complex which moves along the line of light, the spirit complex should return to its home density, in my understanding.
