The Book of Ichigo Ichie

Every moment in our life happens only once, and if we let it slip away, we lose it forever–an idea captured by the Japanese phrase ichigo ichie (pronounced itchy-GO itchy-A). Often spoken in Japan when greeting
someone or saying goodbye, to convey that the encounter is unique and special, it is a tenet of Zen Buddhism and is attributed to a sixteenth-century master of the Japanese tea ceremony, or “ceremony of attention,”
whose intricate rituals compel us to focus on the present moment.
