This "poetic" meaning comes close to several things in Japanese aesthetics and Taoist terms. The closest I can think of is "aware". This is usually used in connection with the Buddhist feeling of "beauty and transience", however there may also be qualities of wabi and sabi connected with it. There may also be a hint of shibui also.
Actually any of these terms may be what Sensei had in mind or something similar.
