Bhagavad Gita · 11.20

द्यावापृथिव्योरिदमन्तरं हिव्याप्तं त्वयैकेन दिशश्च सर्वाः।दृष्ट्वाद्भुतं रूपमुग्रं तवेदंलोकत्रयं प्रव्यथितं महात्मन्॥

dyāvā-pṛthivyor idam antaraṁ hi vyāptaṁ tvayaikena diśhaśh cha sarvāḥ dṛṣhṭvādbhutaṁ rūpam ugraṁ tavedaṁ loka-trayaṁ pravyathitaṁ mahātman

The space between heaven and earth, and all the directions, are pervaded by you alone. Seeing this wondrous and fearsome form of yours, the three worlds tremble, O great soul.
