ŚVETĀŚVATARA UPANISHAD · 4.10

मायां तु प्रकृतिं विद्यान् मायिनं तु महेश्वरं ।
तस्यावयवभूतैस् तु व्याप्तं सर्वं इदं जगत् ॥

māyāṃ tu prakṛtiṃ vidyān māyinaṃ tu maheśvaraṃ ।
tasyāvayavabhūtais tu vyāptaṃ sarvaṃ idaṃ jagat ॥

Know then Prakriti (nature) is Mâyâ (art), and the great Lord the Mâyin (maker); the whole world is filled with what are his members.

F. Max Müller · The Upanishads, Sacred Books of the East 15 (1884)
