CHĀNDOGYA UPANISHAD · 4.8.4

स य एतम् एवं विद्वांश् चतुष्कलं पादं ब्रह्मण आयतनवान् इत्य् उपास्त आयतनवान् अस्मिंल् लोके भवति ।
आयतनवतो ह लोकाञ् जयति य एतम् एवं विद्वांश् चतुष्कलं पादं ब्रह्मण आयतनवान् इत्य् उपास्ते ॥

sa ya etam evaṃ vidvāṃś catuṣkalaṃ pādaṃ brahmaṇa āyatanavān ity upāsta āyatanavān asmiṃl loke bhavati ।
āyatanavato ha lokāñ jayati ya etam evaṃ vidvāṃś catuṣkalaṃ pādaṃ brahmaṇa āyatanavān ity upāste ॥

'He who knows this and meditates on the foot of Brahman, consisting of four quarters, by the name of Âyatanavat, becomes possessed of a home in this world. He conquers the worlds which offer a home, whoever knows this and meditates on the foot of Brahman, consisting of four quarters, by the name of Âyatanavat.'
