By the practice (of Vajrolīmudrā) (abhyāsena), (the Yogī) should draw (āharet) upward (ūrdhvam) (that) Bindu --semen-- (bindum) which is falling --i.e. which is about to fall-- (patat) into the woman's (nārī) vagina (bhage). (If his semen falls,) he should keep (rakṣayet) one's own (nijam) fallen (calitam) Bindu --semen-- (bindum), as well as (the feminine semen or ovarian fluid) (ca), by dragging (them) (ākṛṣya) upward (ūrdhvam)1||87||
