Well, I have to add this, but remember it's me - only my opinion.

Stay away from the base/coxis (sp?)1st chakra/red/pink (whatever). This stirs up 'the beast'. Pet a dog or cat at the base of tail and look what happens. They like it! and not for spiritual reasons.

I give it's due for it is also the furnace - but I won't spend much time or focus there.

Well, another thought. I've been sluggish lately. I might need a tune-up down there.
