nizaRRa
niṣaṇṇa , nt. (not recorded as subst. ), sitting down : gamanaṃ ( mss. gataṃ, unmetr. ) sthitaṃ niṣaṇṇaṃ śayitaṃ lokottaraṃ munino (= Buddhasya) Mv i.167.18 , supra-worldly is the going, standing, sitting, lying of a Buddha (a Lokottaravādin doctrine); note that Skt. ( tho rarely) uses sthita as a noun (like gamana); perhaps this otherwise unknown use of niṣaṇṇa and śayita is influenced by that.
