Bhagavad Gita · 11.45

अदृष्टपूर्वं हृषितोऽस्मि दृष्ट्वाभयेन च प्रव्यथितं मनो मे।तदेव मे दर्शय देव रूपंप्रसीद देवेश जगन्निवास॥

adṛṣhṭa-pūrvaṁ hṛṣhito 'smi dṛṣhṭvā bhayena cha pravyathitaṁ mano me tad eva me darśhaya deva rūpaṁ prasīda deveśha jagan-nivāsa

I am thrilled to have seen what was never seen before, yet my mind trembles with fear. Please show me that familiar form again, O Lord of gods, O refuge of the universe — be gracious!
