CHĀNDOGYA UPANISHAD · 4.7.4

स य एतम् एवं विद्वांश् चतुष्कलं पादं ब्रह्मणो ज्योतिष्मान् इत्य् उपास्ते ज्योतिष्मान् अस्मिंल् लोके भवति ।
ज्योतिष्मतो ह लोकाञ् जयति य एतम् एवं विद्वांश् चतुष्कलं पादं ब्रह्मणो ज्योतिष्मान् इत्य् उपास्ते ॥

sa ya etam evaṃ vidvāṃś catuṣkalaṃ pādaṃ brahmaṇo jyotiṣmān ity upāste jyotiṣmān asmiṃl loke bhavati ।
jyotiṣmato ha lokāñ jayati ya etam evaṃ vidvāṃś catuṣkalaṃ pādaṃ brahmaṇo jyotiṣmān ity upāste ॥

'He who knows this and meditates on the foot of Brahman, consisting of four quarters, by the name of Gyotishmat, becomes full of light in this world. He conquers the worlds which are full of light, whoever knows this and meditates on the foot of Brahman, consisting of four quarters, by the name of Gyotishmat.
