Bhagavad Gita 11.49

Do not be afraid or confused by the terrible vision. Put away your fear and, with a joyful mind, see Me again in My usual form.

मा ते व्यथा मा च विमूढभावो
दृष्ट्वा रूपं घोरमीदृङ्ममेदम्।
व्यपेतभीः प्रीतमनाः पुनस्त्वं
तदेव मे रूपमिदं प्रपश्य॥

mā te vyathā mā ca vimūḍhabhāvo
dṛṣṭvā rūpaṃ ghoramīdṛṅmamedam|
vyapetabhīḥ prītamanāḥ punastvaṃ
tadeva me rūpamidaṃ prapaśya||
