Naraka-varṇana: The Hellish Planets and the Karmic Logic of Punishment
यस्त्विह वै सवर्णां भार्यां द्विजो रेत: पाययति काममोहितस्तं पापकृतममुत्र रेत:कुल्यायां पातयित्वा रेत: सम्पाययन्ति ॥ २६ ॥
yas tv iha vai savarṇāṁ bhāryāṁ dvijo retaḥ pāyayati kāma-mohitas taṁ pāpa-kṛtam amutra retaḥ-kulyāyāṁ pātayitvā retaḥ sampāyayanti.
যদি দ্বিজবংশীয় কোনো মূর্খ ব্যক্তি কামবশে নিজের স্ত্রীকে বীর্য পান করায়, তবে মৃত্যুর পর তাকে 'লালাভক্ষ' নামক নরকে নিক্ষেপ করা হয়। সেখানে তাকে বীর্যের নদীতে ফেলে সেই বীর্য পান করতে বাধ্য করা হয়।
The practice of forcing one’s wife to drink one’s own semen is a black art practiced by extremely lusty persons. Those who practice this very abominable activity say that if a wife is forced to drink her husband’s semen, she remains very faithful to him. Generally only low-class men engage in this black art, but if a man born in a higher class does so, after death he is put into the hell known as Lālābhakṣa. There he is immersed in the river known as Śukra-nadī and forced to drink semen.
In Canto 5, Chapter 26, Śukadeva describes that grave, lust-driven sexual wrongdoing leads to specific hellish reactions, where the sinner is punished in a manner mirroring the offense.
He explains the workings of karma to warn Parīkṣit Mahārāja (and all listeners) against sinful life and to encourage dharma, self-control, and ultimately devotion to the Lord.
It teaches restraint and responsibility in sexuality: avoid lust-driven exploitation, honor dharmic conduct in marriage, and cultivate purity through sādhana (chanting, good association, and regulated life).
