CC Madhya 21.78

dvārakādi — vibhu, tāra ei ta pramāṇa
‘āmāra-i brahmāṇḍe kṛṣṇa’ sabāra haila jñāna
Word for word: 
dvārakā-ādi — Dvārakā-dhāma and other abodes; vibhu — transcendental abode; tāra ei ta pramāṇa — this is the evidence of that; āmāra-i brahmāṇḍe — in my brahmāṇḍa; kṛṣṇa — Kṛṣṇa is now present; sabāra — of all of them; haila jñāna — there was this knowledge.
Translation: 
“This is the proof of Dvārakā’s opulence: all the Brahmās thought, ‘Kṛṣṇa is now staying in my jurisdiction.’
