■ N. in many cases is synonymous with nibbāna & parinibbāna; it may be said to be even a stronger expression as far as the active destruction of the causes of life is concerned. Therefore frequently combined with nibbāna in formula “sabbasankhāra-samatho… virāgo nirodho nibbānaṃ,” e.g. SN.i.136; Iti.88. Nd ii.s. nibbāna (see nibbāna iii.6). Also in combination with nibbidā, e.g. SN.iii.48, SN.iii.223; SN.iii.163 sq. SN.v.438
■ The opposite of nirodha is samudaya, cp formula “yaṃ kiñci samudaya-dhammaṃ sabban taṃ nirodha-dhammaṃ” e.g. Nd ii.under sankhārā & passim
