ŚVETĀŚVATARA UPANISHAD · 5.11

संकल्पनस्पर्शनदृष्टिमोहैर् ग्रासाम्बुवृष्ट्या चात्मविवृद्धिजन्म ।
कर्मानुगान्य् अनुक्रमेन देही स्थानेषु रूपाण्य् अभिसंप्रपद्यते ॥

saṃkalpanasparśanadṛṣṭimohair grāsāmbuvṛṣṭyā cātmavivṛddhijanma ।
karmānugāny anukramena dehī sthāneṣu rūpāṇy abhisaṃprapadyate ॥

By means of thoughts, touching, seeing, and passions the incarnate Self assumes successively in various places various forms, in accordance with his deeds, just as the body grows when food and drink are poured into it.

F. Max Müller · The Upanishads, Sacred Books of the East 15 (1884)
