Brahmacarya-Upāya: Jñāna, Śauca, and the Mind’s Role in Desire (शान्ति पर्व, अध्याय २०७)
ततस्त्रेतायुगे काले संस्पर्शाज्जायते प्रजा । न हाभून्मैथुनो धर्मस्तेषामपि जनाधिप
tatas tretāyuge kāle saṁsparśāj jāyate prajā | na hābhūn maithuno dharmas teṣām api janādhipa ||
பின்னர் திரேதா யுகம் வந்தபோது தொடுதல் மட்டுமால் மக்கள் பிறக்கத் தொடங்கினர்; மனிதர்களின் தலைவனே! அக்காலத்திலும் மைதுன-தர்மம் வழக்கில் வரவில்லை.
भीष्म उवाच
Bhīṣma highlights that dharma and social customs vary by yuga: in earlier ages, procreation was portrayed as occurring through subtler means (mere touch), and sexual union was not yet an established social practice—implying a progressive coarsening of human conduct across ages.
In Bhīṣma’s discourse to the king, he describes conditions in the Tretā-yuga: beings begin to produce offspring through touch alone, and the institution or widespread practice of maithuna (sexual intercourse) is said not to have arisen among people at that time.
