clarifying the direct perception mode

I am a little confused about proto emotions & the direct perception mode
are all proto-emotions to be grounded in the body?
the emphasis seems to be on anxiety and anger
but in his video Kenneth grounds gratitude in case it becomes overwhelming
when I am trying the practice I am at times expereincing strong feelings of universal love, joy and happiness should these be grounded or are they harmless? if they've got to this stage have I missed them and they are already broken off?

Ground those too

All emotions

The goal is "the peace that surpasses all understanding"

OK, this is good stuff. Mu is right that it can (and should) all be grounded. Why? Because the Brahma Viharas have no emotional charge anyway; you cannot get carried away by them and they don't break off. Grounding them does not prevent them from arising, so you can safely ground everything, confident that there is no downside.

Richard, the gratitude I was experiencing in that moment had gone beyond metta, karuna, mudita, etc., and had already morphed into a kind of blubbering sentimentality. At that point, the proto-blob is about to go renegade and once it does it takes on this weird psuedo-identity and develops its own little survival instinct. It perversely sees reunification with the rest of the universe (the main body of wax) as death, so it will do anything to prevent that. And it knows that all it has to do to prevent re-unification is to cause trouble! It has to remain agitated in order to stay alive. It doesn't care what kind of agitation it is, so it is a shape-shifter. It will change from blubbering sentimentality (the near enemy of overwhelming gratitude) into rage and violence in an instant.

This is why in order to know the "peace that surpasses understanding" you have to continuously ground all emotional charge no matter how benign it appears to be in the beginning.
