अर्धदुःखसुखमभ्यनयस्त्वं सास्रुभानुविहसद्विधुनेत्रः ॥ (21, 83)
हे विष्णो ! सूर्यचन्द्रयोः तव नेत्रत्वात् तथा कर्णस्य च सूर्यपुत्रत्वात् तन्नाशे सूर्यस्य शोको अभवत्। अर्जुनस्य चन्द्रवंशस्थत्वात् तस्य विजये चन्द्रः सुखमन्वभवत्। ताभ्याम् अर्धसुखमर्धदुःखाभिनयात् त्वम् अद्भुतरूपोऽसि।
The above sloka is from naishadIya charitam of srI Harsha.
Lord visnu is praised in the above sloka.
Mahavisnu’s two eyes are Chandra and surya. One eye of visnu started watering in grief while the other glowed with pride. In the kurukshetra battle, when Arjuna kills karna as adviced by lord Krishna, Chandra beams with pride as Arjuna belongs to the Chandra vamsa. And
Surya weeps in grief as karna is his son.
अर्कसुतः-son of surya, कर्णः-karna, दयालुः-the compassionate one, घातितः- killed in the battle, इन्दुकुलपार्थः- pArtha or arjuna , who belongs to the Chandra vamsa, जैत्रितः –was given the victory, कृतार्थः- by this the purpose of Krishna avataara is fulfilled, त्वं – you lord visnu, नेत्रः- your eyes, अभ्यनयः – were showing both, अर्धसुखं- happiness,and अर्धदुःखं-sorrow, ( the eyes of lord visnu are surya nad Chandra) भानुः –the sun , सास्रुः- was with tears (as his son karna was killed in the battle), विधुः – , Chandra, विहसत् – was smiling( as arjuna got the victory), ।
The victory of Arjuna and the death of karna is a known story. But the poet has imagined and brought it out in a creatively unique point of view.
