Does anyone recognise this haiku?

I was staying at samye ling Tibetan monastery in Scotland and writing a lot of poetry. I wrote this haiku in one go without any consideration or counting syllables, and did not feel as if I wrote it. It is much better than my usual standard: Palms open fingers spread, Serenity offered, The mind now awake. Does anyone recognise it? I am certain that I have no conscious memory of reading these words or any similar lines and am equally sure that they are not my invention! I would appreciate any insight into how they came to be. I have not subsequently experienced anything like this.
