Bhagavad-gītā As It Is · Text 11.15
Arjuna prays in astonishment and reverence
अर्जुन उवाच
पश्यामि देवांस्तव देव देहे
सर्वांस्तथा भूतविशेषसङ्घान् ।
ब्रह्माणमीशं कमलासनस्थ-
मृषींश्च सर्वानुरगांश्च दिव्यान् ॥ १५ ॥
arjuna uvāca
paśyāmi devāṁs tava deva dehe
sarvāṁs tathā bhūta-viśeṣa-saṅghān
brahmāṇam īśaṁ kamalāsana-stham
ṛṣīṁś ca sarvān uragāṁś ca divyān
Arjuna said: My dear Lord Kṛṣṇa, I see assembled in Your body all the demigods and various other living entities. I see Brahmā sitting on the lotus flower, as well as Lord Śiva and all the sages and divine serpents.
