तत्र वस्तुद्वयं वक्ष्ये दुर्लभं यस्य कस्यचित्। क्षीरं चैकं द्वितीयं तु नारी च वशवर्तिनी॥८४॥

With respect to that --i.e. to the practice of Vajrolī-- (tatra), I will speak (vakṣye) about a couple (dvayam) of things (vastu) hard to be obtained (durlabham) to whosoever (yasya kasyacid) (is poor)1: One (thing) (ekam) (is) milk (kṣīram ca) and (ca) the second (dvitīyam) (is) truly (tu) a woman (nārī) that acts obediently (vaśa-vartinī)2||84||
