CC Madhya 21.8

ei-mata ṣaḍ-aiśvarya, sthāna, avatāra
brahmā, śiva anta nā pāya — jīva kon chāra
Word for word: 
ei-mata — such; ṣaṭ-aiśvarya — six opulences; sthāna — abode; avatāra — incarnations; brahmā — Lord Brahmā; śiva — Lord Śiva; anta pāya — cannot find the limit; jīva — a living entity; kon — what of; chāra — worthless.
Translation: 
“Each Vaikuṇṭha planet is full of spiritual bliss, complete opulence and space, and each is inhabited by incarnations. If Lord Brahmā and Lord Śiva cannot estimate the length and breadth of the spiritual sky and the Vaikuṇṭha planets, how can ordinary living entities begin to imagine them?
