The Japanese idiom 一期一会 ichigo ichie literally translates to “one opportunity, one encounter.” The meaning of this idiom is to treasure every encounter, for it will never recur.
The idiom is derived from Zen Buddhism, and is particularly associated with the Japanese tea ceremony or sadou 茶道. In the context of sadou, ichigo ichie reminds participants that each tea ceremony is unique that will never recur in one’s lifetime, and thus each moment should be treated with the utmost sincerity.
In the context of daily life, think of each encounter as a once-in-a-lifetime chance. So, why not seize the day?
