Being aware of your breath forces you into the present moment – the key to all inner transformation. Whenever you are conscious of the breath, you are absolutely present. You may also notice that you cannot think and be aware of your breathing. Conscious breathing stops your mind. But far from being in a trance or half asleep, you are fully awake and highly alert. You are not falling below thinking, but rising above it. And if you look more closely, you will find that those two things – coming fully into the present moment and ceasing thinking without loss of consciousness – are actually one and the same: the arising of space consciousness.
~ Eckhart Tolle
