Karṇa’s advance against the Pāṇḍava host; Arjuna’s clash with the Saṃśaptakas (कर्णस्य पाण्डवसेनाप्रवेशः—अर्जुनस्य संशप्तकसंप्रहारः)
ततो वर्षसहस्रे तु समेष्याम: परस्परम् । एकीभावं गमिष्यन्ति पुराण्येतानि चानघ
tato varṣasahasre tu sameṣyāmaḥ parasparam | ekībhāvaṃ gamiṣyanti purāṇy etāni cānagha, nibodha manasā cātra na te kāryā vicāraṇā |
दैत्यों ने कहा— “हे अनघ! फिर एक हजार वर्ष पूर्ण होने पर हम परस्पर मिलेंगे। तब ये तीनों पुर एकत्र होकर एकीभाव को प्राप्त होंगे। उस समय जो एक ही बाण से इन तीनों पुरों को नष्ट कर सके, वही देवेश्वर हमारी मृत्यु का कारण हो।”
दुर्योधन उवाच
The verse stresses unwavering comprehension of a destined condition: when separate powers unite into a single vulnerable moment (ekībhāva), the decisive outcome becomes possible; therefore one should not waver in doubt about the stated law/condition.
Duryodhana recounts a prior mythic account about the three puras: after a thousand years they will meet and become one; he urges the listener to grasp this firmly, since the later destruction of the united forts depends on this specific alignment.
