discrimination; historical poetic school
In literary history, refers to a school of waka poetics that valued conscious artistry and intellectual depth, as opposed to the 'artless' 無心 (むしん) style. The 'discrimination' gloss reflects the idea of deliberate, discerning composition.
Ushin and mushin are important concepts in medieval waka poetry.
attachment; distractions
Buddhist term for mental attachments or worldly distractions that hinder enlightenment.
In Buddhism, cutting off attachments of the mind is considered the path to enlightenment.
無心 describes a mind free of deliberate thought, while 有心 is the Buddhist term for a mind still caught up in conscious intention.
From 有 (u, 'to have, exist') + 心 (shin, 'mind, heart'). The exact historical derivation is uncertain; the term is used in both literary and Buddhist contexts.
