brahmacaryeṇa saṁtiṣṭhed apramādena maskarī
brahmacaryeṇa saṁtiṣṭhed apramādena maskarī |
darśanaṁ sparśanaṁ keliḥ kīrtanaṁ guhya-bhāṣaṇam ||
saṅkalpo’dhyavasāyaś ca kriyā-nivṛtttir eva ca |
etan maithunam aṣṭāṅgaṁ pravadanti manīṣiṇaḥ ||
viparītaṁ brahmacaryam anuṣṭheyaṁ mumukṣubhiḥ |
(Kaṭharudra Upaniṣad: 8.9–11)
“A sannyāsī (maskarī) should observe brahmacarya with vigilance. Looking, touching, playing [alt., joking], mentioning, conversing privately, fancying, pursuing, and completion of the act [itself]—the wise say these are the eight aspects of intercourse. The opposite [of these eight], brahmacarya, is to be practiced by seekers of mukti.”
