Under that title Kawabata talked about a unique kind of mysticism which is found not only in Japanese thought but also more widely Oriental thought. By 'unique' I mean here a tendency towards Zen Buddhism. Even as a twentieth-century writer Kawabata depicts his state of mind in terms of the poems written by medieval Zen monks. Most of these poems are concerned with the linguistic impossibility of telling truth. According to such poems words are confined within their closed shells. The readers can not expect that words will ever come out of these poems and get through to us. One can never understand or feel sympathetic towards these Zen poems except by giving oneself up and willingly penetrating into the closed shells of those words.
