Saubha-ākhyāna: Śālva’s Approach and the Fortification of Dvārakā (सौभाख्यानम्—द्वारकायाः सुरक्षाविधानम्)
तस्मिन् विनिहते वीरे गदानुन्ने महासुरे । प्रविश्य महतीं सेनां योधयामास मे सुत:,गदासे घायल हुए उस वीर महादैत्यके मारे जानेपर मेरा पुत्र साम्ब शाल्वकी विशाल सेनामें घुसकर युद्ध करने लगा
tasmin vinihate vīre gadānunne mahāsure | praviśya mahatīṃ senāṃ yodhayāmāsa me sutaḥ ||
その英雄たる大アスラが棍棒に打ち倒され、ついに討たれるや、わが子は広大な軍勢の中へ躍り込み、戦いを始めた。この段は、恐るべき勇士が倒れても戦は止まらず、義務（ダルマ）と決意が次なる戦士を修羅の渦へと押し出すことを示している。

The verse highlights steadfastness in duty amid violence: even after a major foe falls, responsibility and resolve compel the next warrior to act. It reflects the Mahābhārata’s recurring ethic of perseverance and role-based obligation in a battlefield context.
After a mighty asura (demon-like warrior) is killed—having been struck down by a mace—the speaker (Vāyudeva) says that his son enters the large army and begins fighting, escalating the battle rather than ending it.
