Bhagavad Gita 11.49

मा ते व्यथा मा च विमूढभावो दृष्ट्वा रूपं घोरमिदृङ्ममेदम् |
व्यपेतभि: पितना: पुनस्त्वं तदेव मे रूपमिदं प्रापश्य

Translation

Be neither afraid nor bewildered on seeing this terrible form of Mine. Be free from fear and with a cheerful heart, behold Me once again in My personal form.
