To concentrate on our breathing means to focus deeply on our inhalations and exhalations – one by one – moment to moment. Consider the tenses that exist in a breath. Every exhale is the past tense of our inhalations. The following inhale is simultaneously the present moment and the past tense of our exhalation. As we inhale, the exhale to follow is the future – it will happen.
The important thing to remember is that one day, embedded in the present moment of an exhalation will also be your last moment. Your last moment. Moments will continue without a moment’s pause. This reality is not a display of the cruelty of life. It’s just the definition of reality: “the world or the state of things as they actually exist, as opposed to an idealistic or notional idea of them.”
