Mandukya Karika, verse 3.28

Text

असतो मायया जन्म तत्त्वतो नैव युज्यते ।
वन्ध्यापुत्रो न तत्त्वेन मायया वाऽपि जायते ॥ २८ ॥

asato māyayā janma tattvato naiva yujyate |
vandhyāputro na tattvena māyayā vā'pi jāyate || 28 ||

28. The unreal cannot be born either really or through Māyā. For the son of a barren woman is born neither in reality nor in illusion.

Shankara Bhashya (commentary)

There are those who hold that all entities are unreal, that the non-existent produces this world. But production, by the non-existent, of any thing either in reality or in illusion is not possible. For we know nothing like it in our experience. As the son of a barren woman is not seen to be born either really or through Māyā, the theory of the non-existence of things is in truth1 untenable.
