Ramayana 5.21.24

रामस्य धनुषः शब्दं श्रोष्यसि त्वं महास्वनम्।।।।शतक्रतुविसृष्टस्य निर्घोषमशनेरिव।

rāmasya dhanuṣaḥ śabdaṃ śroṣyasi tvaṃ mahā-svanam | śatakratu-visṛṣṭasya nirghoṣam aśaner iva ||

You will hear the mighty, dreadful twang of Rāma’s bow—like the thunderous rumble of the lightning-bolt released by Śatakratu (Indra).
