accusative singular masculine form of byasana (resolving apparent spelling) or locative singular neuter form byasane with enclitic -ñ(h)et(a)ṁ; the form is unusual and may be a textual variant for byasanaṁ hetaṁ 'because of affliction' or a contraction
Analysis. byasana (by- + √as) + hetaṁ (instrumental/locative postposition 'because of'). The spelling suggests vi-āsana or a corruption; likely means 'because of affliction/loss of prosperity'.
Etymology. byasana may derive from vi-āsana (vi 'apart' + ā 'toward' + √as 'sit'), giving 'being displaced, overthrown condition', hence affliction and loss. Alternatively, from a root meaning 'broken, wasted'. The word appears in canonical texts to denote material ruin, misfortune, and by extension mental affliction.
