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.

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.
