CC Madhya 20.169

saubhary-ādi-prāya sei kāya-vyūha naya
kāya-vyūha haile nāradera vismaya nā haya
Word for word: 
saubhari-ādi — beginning with the sage named Saubhari; prāya — like; sei — that; kāya-vyūha — the expansion of one’s body; naya — is not; kāya-vyūha — expansions of the body; haile — if there are; nāradera — of Nārada Muni; vismaya — the astonishment; nā haya — there cannot be.
Translation: 
“The prābhava-prakāśa expansions of Lord Kṛṣṇa are not like the expansions of the sage Saubhari. Had they been so, Nārada would not have been astonished to see them.
