CHĀNDOGYA UPANISHAD · 8.2.10

यं यम् अन्तम् अभिकामो भवति ।
यं कामं कामयते ।
सो ऽस्य संकल्पाद् एव समुत्तिष्ठति ।
तेन संपन्नो महीयते ॥

yaṃ yam antam abhikāmo bhavati ।
yaṃ kāmaṃ kāmayate ।
so ’sya saṃkalpād eva samuttiṣṭhati ।
tena saṃpanno mahīyate ॥

'Whatever object he is attached to, whatever object he desires, by his mere will it comes to him, and having obtained it, he is happy.
