The affixes ṇa and ḍhañ come in the sense of 'good for that' after the words sarva and puruṣa,
This debars 'chha'. Thus सर्वस्मै हितं = सार्वम्. So also पौरुषेयम् ॥
Vart:- The affix ण comes optionally after सर्व, as, सर्वीयम् or सार्वम् ॥
Vart:- The affix ढञ् comes after पुरुष when the word so formed means: 'slaughter', 'modification', 'a crowd', or 'made by him'. As पौरुषेयो वधः &c. 'man-slaughter', 'a crowd of men', 'human action', 'made by man'. e.g. पौरुषेयो ग्रन्थः 'a book written by man' contra. अपौरुषेया वेदाः 'The Vedas are non-human'.,
