Why is LOO the purest spiritual source?

[Infinite]

I found a very important answer of Latwii:

Carla: Could you give a subjective opinion as to the degree of distortion from the information Ra might give which would be present in information from L/Leema? In other words, how watered-down or distorted would this information be?

I am Latwii, and we find that this query is one with variable possibilities of response due to the factors which would comprise each session. These factors would be variable according to the entities present, their interest in this kind of information, the general level of vital energy, of all present for the session and the preparations in the way of study, shall we say, that had gone into the, shall we say, mental and emotional computations prior to the sessions. In general, we may suggest that the degree of accuracy that could be hoped for would be seventy-five to eighty percent in relation to the accuracy that was achieved in the contact with those known as Ra.

That's a good percent for me. I believe that Q'uo informations are less distorted than Latwii.
