बालकाण्ड ५६: विश्वामित्र–वसिष्ठ अस्त्रसंघर्षः (Visvamitra and Vasistha: Contest of Divine Weapons)
तदस्त्रमुद्यतं दृष्ट्वा देवास्साग्निपुरोगमा:।।1.56.14।।देवर्षयश्च सम्भ्रान्तागन्धर्वास्समहोरगा:।त्रैलोक्यमासीत्सन्तप्तं ब्रह्मास्त्रे समुदीरिते।।1.56.15।
tad astram udyataṃ dṛṣṭvā devāḥ sāgnipurogamāḥ | devarṣayaś ca sambhrāntā gandharvāḥ saha mahoragāḥ || 1.56.14 ||
Seeing that weapon raised, the gods—with Agni at their head—along with the divine seers, the Gandharvas, and the great serpents, were thrown into alarm.
All the devatas, with Agni in the forefront, divine rishis, great uragas and gandharvas were agitated seeing the Brahmastra raised. When Brahmastra was discharged, the three worlds became distressed.
Dharma includes safeguarding cosmic order; when ultimate weapons are invoked, even divine beings tremble—implying such power must be used only with strict moral necessity.
As the Brahmāstra is raised, the wider cosmos reacts: gods, sages, celestial musicians, and nāgas become alarmed.
The verse emphasizes reverence for limits: recognition (by all beings) that certain powers are catastrophic if misused.
