CC Ādi 5.64

kṛṣṇa — kartā, māyā tāṅra karena sahāya
ghaṭera kāraṇa — cakra-daṇḍādi upāya
Word for word: 
kṛṣṇa — Lord Kṛṣṇa; kartā — the creator; māyā — material energy; tāṅra — His; karena — does; sahāya — assistance; ghaṭera kāraṇa — the cause of the earthen pot; cakra-daṇḍa-ādi — the wheel, the rod, and so on; upāya — instruments.
Translation: 
Lord Kṛṣṇa is the creator, and māyā only helps Him as an instrument, just like the potter’s wheel and other instruments, which are the instrumental causes of a pot.
