Rājā–Rāja-Śabda-Prabhavaḥ — The Origin and Rationale of Kingship and Daṇḍanīti
तांस्तु कामवशं प्राप्तान् रागो नाम समस्पृशत् । रक्ताश्न नाभ्यजानन्त कार्याकार्ये युधिष्ठिर
tāṁs tu kāmavaśaṁ prāptān rāgo nāma samaspṛśat | raktāś ca nābhyajānanta kāryākārye yudhiṣṭhira ||
毗湿摩说道：那些人一旦落入欲望的支配，便被贪染之情（rāga）所攫住。被其炽热所灼，噢，坚战啊，他们再也不能分辨何者当为，何者不当为。

Educational Q&A
When desire takes control, it gives rise to attachment/passion (rāga), which clouds judgment; a person then loses the ability to distinguish kārya (duty/right action) from akārya (wrong/forbidden action).
In Bhishma’s instruction to Yudhishthira in the Shanti Parva, he explains how people who become dominated by desire are overtaken by passion, and in that state they fail to recognize what is ethically required versus what is prohibited.
