MUṆḌAKA UPANISHAD · 2.1.2
दिव्यो ह्यमूर्तः पुरुषः सबाह्याभ्यन्तरो ह्यजः ।
अप्राणो ह्यमनाः शुभ्रो ह्यक्षरात्परतः परः ॥ २॥
divyo hyamūrtaḥ puruṣaḥ sabāhyābhyantaro hyajaḥ ।
aprāṇo hyamanāḥ śubhro hyakṣarātparataḥ paraḥ ॥ 2॥
He, the divine, the formless Spirit, even he is the outward and the inward and he the Unborn; he is beyond life, beyond mind, luminous, Supreme beyond the immutable.
Sri Aurobindo · CWSA 18, p. 137
