PRAŚNA UPANISHAD · 3.3

आत्मन एष प्राणो जायते । यथैषा पुरुषे
छायैतस्मिन्नेतदाततं
मनोकृतेनायात्यस्मिञ्शरीरे ॥ ३.३॥

ātmana eṣa prāṇo jāyate । yathaiṣā puruṣe
chāyaitasminnetadātataṃ
manokṛtenāyātyasmiñśarīre ॥ 3.3॥

“Of the Spirit is this breath of Life born; even as a shadow is cast by a man, so is this Life extended in the Spirit and by the action of the Mind it entereth into this body.
