CC Madhya 20.269

kāraṇābdhi-pāre māyāra nitya avasthiti
virajāra pāre paravyome nāhi gati
Word for word: 
kāraṇa-abdhi-pāre — on one bank of the Causal Ocean; māyāra — of the material energy; nitya — eternal; avasthiti — position; virajāra pāre — on the other bank of the Virajā, or the Causal Ocean; para-vyome — in the spiritual world or sky; nāhi — there is not; gati — admission.
Translation: 
“The Virajā, or Causal Ocean, is the border between the spiritual and the material world. The material energy is situated on one shore of that ocean, and it cannot enter onto the other shore, which is the spiritual sky.
