Soulmates

Proverb for May: 一期一会
Google Translation: Once in a while
“一期一会 (ichigo ichie)” means once-in-a-lifetime meeting and is based on a saying from the Azuchi-Momoyama period by Yamanoue Soji, a disciple of tea master Sen no Rikyu. The phrase originates from the spirit of the tea ceremony and implies that since the encounter at the tea ceremony on that day comes only once in a lifetime, one should cherish it and treat people with a sincere heart.
It is deeply related to Buddhism as well since “一期 (ichigo)” is a Buddhist term meaning from birth to death, and “一会 (ichie)” refers to a gathering or meeting mainly at a Buddhist memorial service. http://kotowaza-allguide.com/i/ichigoichie.html
