कर्णपरर्वणि त्रयोचत्वारिंशदध्यायः (Karṇa-parva Adhyāya 43) — Kṛṣṇa’s Battlefield Assessment and the Reversal Around Bhīma
तत्र सम राक्षसी गाति सदा कृष्णचतुर्दशीम्
tatra sama rākṣasī gāti sadā kṛṣṇa-caturdaśīm
There, that rākṣasī regularly observes Kṛṣṇa-caturdaśī—the fourteenth lunar day of the dark fortnight.
कर्ण उवाच
The verse highlights that actions can become habitual and time-bound: even a rākṣasī is portrayed as following a fixed observance tied to a lunar day. The ethical implication is that discipline or ritual regularity is value-neutral—its moral worth depends on the intention and the ends it serves.
Karṇa, while speaking, refers to a rākṣasī and notes her consistent association with (or observance on) Kṛṣṇa-caturdaśī, using the calendrical marker to characterize her behavior as recurrent and ominously patterned.
