Now THIS is REALLY INTERESTING!!

everything, even the gratitude of the buyer would probably be in the dominance of the orange ray to yellow ray.

Hardly so, I believe. It seems you view this whole process from a negative light, as in it's not possible to adequately be free from lower energies, but I think it is highly dependent on various factors. As 3DM points out much of it is dependent on the receiver and their ability to process the energies at play. Two people can attend a conference and be led in two very different directions. How is it that one can be misled/distorted and another can't? The information is the same, so our ability to process the situation through our distortions and blockages can be completely independent of the speaker.

However, the slippery aspect of this is that many do have distortions that prevent them from understanding the information clearly, and as you have said many spiritual teachers are victims of this themselves. They are caught up in their own lower energies which pollutes the whole process. But all of this isn't a money issue at all, it is a more complex orange/yellow energy issue involving the teach/learning process that can be influenced by money.

So what about those that are free from lower energies? Again, I still stand by intention as being the significant factor. If you are operating and perceiving from higher rays, that is where the transfer takes place if both have the corresponding centers activated. Throw in the money factor, and you simply taint it. Information can't come under the dominance of lower energies if that's not how you perceive it.

How we view the interaction taking place of the one charging for something is a complex interplay between both involved. It simply isn't an issue of higher energies being under the influence of the lower.

Have you ever noticed that the more a teacher communicates their intentions and understandings with clarity the obvious result is less distortion? Simply paying to attend a seminar doesn't undermine the strength and brilliance of the love and wisdom being sent out if you clearly dissolve the nature of the lower energies at play as best as possible.

It would seem the issue lies more in aligning yourself properly as a teach/learner.
