नलदमयन्त्युपाख्यानम्—नलप्रशंसा हंसदूतवृत्तान्तः
Nala–Damayantī Upākhyāna: Praise of Nala and the Swan-Messenger Episode
इति श्रीमहाभारते वनपर्वणि इन्द्रलोकाभिगमनपर्वणि पार्थाहारक थने पज्चाशत्तमोडध्याय:
iti śrīmahābhārate vanaparvaṇi indralokābhigamanaparvaṇi pārthāhārakathane pañcāśattamo 'dhyāyaḥ
Así, en el Śrī Mahābhārata, dentro del Vana Parva—en particular, en la sección relativa al viaje al mundo de Indra—concluye el capítulo quincuagésimo, en el episodio concerniente al sustento de Pārtha (Arjuna). Este colofón señala un punto de transición en la narración, marcando el cierre de una unidad de enseñanza y relato que enmarca la disciplina de Arjuna y el arco moral mayor de la resistencia y el esfuerzo justo durante el destierro.
वैशम्पायन उवाच
As a colophon, the verse primarily teaches how the epic frames moral instruction through carefully bounded narrative units: the completion of a chapter reminds the listener that disciplined conduct (especially in exile) and purposeful striving toward higher aims (here, the Indraloka-journey context) are to be contemplated as coherent lessons within dharma.
This is the formal closing line of Vana Parva, Adhyāya 50, identifying the larger book (Vana Parva), the sub-section (Indralokābhigamana-parvan), and the episode focus (the narration concerning Pārtha/Arjuna’s sustenance), and marking the end of the chapter in Vaiśampāyana’s recitation.
