Oh, there are so many things I could say about this one. Almost half of them are uninformed opinions that shouldn't be spoken in public yet, if ever, and the other half are none of your business...

That's us crossing that threshold between us the experiencers and Us the Creators, that mad cackle of glee that almost-but-not-quite manages to escape as we feel the powers flow through us and the magic takes effect. It's wrapped in intent, and sheathed in desires, filtered through attachment, but at essence most raw it is the urge to have fun.
Lust. Passion. The frictional catalysis of the Work..
