informal kasaya; informal Buddhist robe
A rare term for a simplified, informal kasaya (Buddhist robe) worn mainly by Pure Land Buddhist adherents. Not part of everyday vocabulary.
See also: 袈裟
Among Pure Land Buddhist monks, some use a simplified kasaya called igiboso.
Compound of 威儀 (dignified bearing, proper conduct) and 細 (thin, fine, informal). The exact historical derivation is uncertain, but the term likely refers to a simplified robe that still maintains proper form.
