MUṆḌAKA UPANISHAD · 3.1.10

यं यं लोकं मनसा संविभाति
विशुद्धसत्त्वः कामयते यांश्च कामान् ।
तं तं लोकं जयते तांश्च कामांस्तस्मादात्मज्ञं ह्यर्चयेद्भूतिकामः ॥ १०॥

yaṃ yaṃ lokaṃ manasā saṃvibhāti
viśuddhasattvaḥ kāmayate yāṃśca kāmān ।
taṃ taṃ lokaṃ jayate tāṃśca kāmāṃstasmādātmajñaṃ hyarcayedbhūtikāmaḥ ॥ 10॥

Whatever world the man whose inner being is purified sheds the light of his mind upon, and whatsoever desires he cherishes, that world he takes by conquest, and those desires. Then, let whosoever seeks for success and well-being approach with homage a self-knower.

Sri Aurobindo · CWSA 18, p. 144
