Bhagavadgita 11.49

11.49

mā te vyathā mā ca vimūḍhabhāvo; dṛṣṭvā rūpaṃ ghoram īdṛṅ mamedam
vyapetabhīḥ prītamanāḥ punas tvaṃ; tad eva me rūpam idaṃ prapaśya

The Deity said:
O Arguna! being pleased (with you), I have by my own mystic power shown you this supreme form, full of glory, universal, infinite, primeval, and which has not been seen before by any one else but you, O you hero among the Kauravas! I cannot be seen in this form by any one but you, (even) by (the help of) the study of the Vedas, or of sacrifices, nor by gifts, nor by actions, nor by fierce penances. Be not alarmed, be not perplexed, at seeing this form of mine, fearful like this. Free from fear and with delighted heart, see now again that same form of mine.
