Bhagavad Gita 11.23 — The worlds are frightened
रूपं महत्ते बहुवक्त्रनेत्रं महाबाहो बहुबाहूरुपादम्। बहूदरं बहुदंष्ट्राकरालं दृष्ट्वा लोकाः प्रव्यथितास्तथाहम् ॥
rūpaṃ mahatte bahuvaktranetraṃ mahābāho bahubāhūrupādam | bahūdaraṃ bahudaṃṣṭrākarālaṃ dṛṣṭvā lokāḥ pravyathitāstathāham ||
Meaning
Seeing your vast form, mighty-armed one, with many mouths and eyes, many arms, thighs and feet, many bellies and terrible tusks, the worlds are frightened, and so am I.
