BṚHADĀRAṆYAKA UPANISHAD · 4.4.24
स वा एष महान् अज आत्मान्नादो वसुदानः ।
विन्दते वसु य एवं वेद ॥
sa vā eṣa mahān aja ātmānnādo vasudānaḥ ।
vindate vasu ya evaṃ veda ॥
This indeed is the great, the unborn Self, the strong, the giver of wealth. He who knows this obtains wealth.
F. Max Müller · The Upanishads, Sacred Books of the East 15 (1884)
