"When things are shaky and nothing is working, we might realise that we are on the verge of something. We might realise that this is a very vulnerable and tender place, and that tenderness can go either way. We can shut down and feel resentful or we can touch in on that throbbing quality. There is definitely something tender and throbbing about groundlessness." - Pema Chodron
(And before you start sniggering - she's a Buddhist nun).
