Night was coming on. I perceived the sky, some stars, and a little greenery. This first sensation was a delicious moment. I still had no feeling of myself except as being "over there". I was born into life at that instant, and it seemed to me that I filled all the objects I perceived with my frail existence. Entirely absorbed in the present moment, I remembered nothing; I had no distinct notion of my person nor the least idea of what had just happened to me; I knew neither who I was nor where I was; I felt neither injury, fear, nor worry. I watched my blood flow as I would have watched a brook flow, without even suspecting that this blood belonged to me in any way. I felt a rapturous calm in my whole being; and each time I remember it, I find nothing comparable to it in all the activity of known pleasures.
Illness and injury can definitely under certain circumstances bring about something akin to a state of ecstasy. I experienced this first hand a few years ago when recovering from a particularly virulent virus I caught on a plane flying back from Venice. There was a turning-point day when the virus receded - and I felt an overwhelming, cathartic feeling of immense calm and tranquillity.
