Josh, I don't have that. If anything, the pleasant skin sensations feel consistently warm in some way.
Jeff, I've noticed a change in the way colors are perceived (richer, perhaps some slight hue shift). Sounds are experienced as if they were clearer as well, but I don't know if this is an actual change or what (whereas the change in colors is something that I could attempt to quantify if necessary; I would not know how to do this for sound). Thanks for pointing out the possibility of a connection between these pleasant sensations and other modalities. (However, I have no idea what to make of the auras etc. you describe.)
Steph, as best as I can describe it (given whatever limitations or confusion there may be in my perspective), I think "the universe experiencing itself" refers to the fact that every sensation exists as a sensation in the universe and not as a sensation that exists in a subject, and recognizing it means seeing that in a direct, experiential, non-reflective way. Richard would cringe, but the direct experience of this is rather mystical (in a completely down-to-earth way).

Jake, in the tradition you describe, are all sensations (not just body sensations) inherently pleasurable in the same sense of "pleasurable"? For example, are visual experiences inherently pleasurable in the same way that skin sensations are? If so, can you say more about this? (I've been thinking about this somewhat recently, and input would be appreciated.)
