When I used to work with my teacher, very occasionally, maybe twice a year, in the heat of a really intense moment, my legs would buckle beneath me and I would collapse. It would happen very suddenly, but I would always get the sense that it was a terrified response to an immensity that had suddenly appeared, and then as quickly disappeared. I now realise that that was Reality – a total openness – and the work is all about becoming strong and sober enough to live in that realm (or at least very close by) permanently.
