This might sound a touch weird - it does to me, and it came from me! Make of it what you will. Profound, dumb, useful, nonsense, it doesn't matter...
When we talk of practice, the problems, the sufferings we endure, the conflicts we experience and the wonderings, the questions, the searching for answers, the mindless wandering, the mindful progressions, the good times, the bad spells...sometimes we forget to breathe.
When you get a moment of quiet, breathe in slowly, deeply, then let it go. Enjoy that ability. You won't have it forever. Savour the bliss of that moment.
