Bhagavad Gita Chapter 11.49
mā te vyathā mā ca vimūḍha-bhāvo
dṛṣṭvā rūpaṁ ghoram īdṛṅ mamedam
vyapeta-bhīḥ prīta-manāḥ punas tvaṁ
tad eva me rūpam idaṁ prapaśya
You have been perturbed and bewildered by seeing this horrible feature of Mine. Now let it be ﬁnished. My devotee, be free again from all disturbances. With a peaceful mind you can now see the form you desire.
