So, what does penetrating the veil truly entail?

[Zachary]

Besides, I love how Ra answers the followup:

89.40 Questioner: What was the attitude of these two entities after they graduated into fourth-density negative and, the veil being removed, they realized that they had switched polarities?

Ra: I am Ra. They were disconcerted.

Sometimes I suspect Ra has a very dry\deadpan sense of humor.  Either way, I feel like the Wanderers in question must have made a deliberate decision to remain negative since, having recalled what they used to be, they must have been in a position to decide which "path" to head down in their future work.

It's my understanding that this was simply the most accurate answer for Ra to give- no humor involved. 

They met the requirement for a negative harvest through STS actions in the form of slaughtering other-selves. This placed them in a negative time/space where the only option for them was to go forward with the path they had chosen while incarnate. Due to the particular Laws in place they had no choice but to move forward on the negative path, being in a negative time/space, until they could accumulate enough polarity to began a reversal process; this is karma. Having entered the negative time/space and going through the life review/regaining memory of their previous polarity, it was rather shocking and unsettling for them due to the extremeness of the perceived "misstep" (I am assuming) in relation to the plan they had prior to incarnating on Venus.
