I need to elucidate my current idea on this. I mean, the concept of "failure to learn" might not be very self-explanatory, I must admit.The basic cause is self-explanatory: failure to learn.
Ra says about the pre-veiling (long wave cycle):
Questioner: ... Before the veil there was an awareness of the need for polarization towards service to others in third density by all entities, whether incarnate in third-density, yellow-ray bodies or in between incarnations. I assume, then, that the condition of which we earlier spoke, one of wealth you might say, was present through the entire spectrum of experience whether it might be between incarnations or during incarnations and the entities just simply could not manifest the desire to create this polarization necessary for graduation. Is this correct?
Ra: I am Ra. You begin to grasp the situation. Let us continue the metaphor of the schooling but consider the scholar as being an entity in your younger years of the schooling process. The entity is fed, clothed, and protected regardless of whether or not the schoolwork is accomplished. Therefore, the entity does not do the homework but rather enjoys playtime, mealtime, and vacation. It is not until there is a reason to wish to excel that most entities will attempt to excel.
Questioner: You have stated in a much earlier session that it is necessary to polarize more than 50% service-to-others to be harvestable fourth-density positive. Was this condition the same at the time before the veil?
Ra: I am Ra. This shall be the last full query of this working.
The query is not answered easily, for the concept of service to self did not hold sway previous to what we have been calling the veiling process. The necessity for graduation to fourth density is an ability to use, welcome, and enjoy a certain intensity of the white light of the One Infinite Creator. In your own terms at your space/time nexus this ability may be measured by your previously stated percentages of service.
Prior to the veiling process the measurement would be that of an entity walking up a set of your stairs, each of which was imbued with a certain quality of light. The stair upon which an entity stopped would be either third-density light or fourth-density light. Between the two stairs lies the threshold. To cross that threshold is difficult. There is resistance at the edge, shall we say, of each density. The faculty of faith or will needs to be understood, nourished, and developed in order to have an entity which seeks past the boundary of third density. Those entities which do not do their homework, be they ever so amiable, shall not cross.
The C's say about the transition from the long to short wave cycle:
The necessity to form the short wave cycle was brought about through nature through the natural bounds of the universe when the group mind of souls chose to experience physicality as opposed to a completely ethereal existence.
There were 4D efforts to entice us to physicality, followed by the enslaving genetic manipulation of DNA, etc.
This was also a transition from STO to STS, and it's also called the "fall". I don't know if the transition from STO to STS was the fall per se, or if the term fall is more about our becoming enslaved by the Lizzies, or the two is more or less the same? I wonder if it was also a possibility to go on with STO in the short wave cycle if it was not for our "alignment" with 4D STS.
Anyway, apparently we were enticed by the "pleasures of physicality", then kind of allowed ourselves to be manipulated by 4D STS, and this resulted in a kind of enslavement.
I think that Ra's description about our pre-fall (long wave cycle) problem of corruption/spoiledness is more or less valid in our short wave experience as well. I want to remind the following again from Ra:
The faculty of faith or will needs to be understood, nourished, and developed in order to have an entity which seeks past the boundary of third density.
I think this problem (the lack of necessary faith or will) is the main reason for the excessive repetition of 3D.
