ŚVETĀŚVATARA UPANISHAD · 5.2

यो योनिं योनिम् अधितिष्ठत्य् एको विश्वानि रूपाणि योनीश् च सर्वाः ।
ऋषिं प्रसूतं कपिलं यस् तम् अग्रे ज्ञानैर् बिभर्ति जायमानं च पश्येत् ॥

yo yoniṃ yonim adhitiṣṭhaty eko viśvāni rūpāṇi yonīś ca sarvāḥ ।
ṛṣiṃ prasūtaṃ kapilaṃ yas tam agre jñānair bibharti jāyamānaṃ ca paśyet ॥

It is he who, being one only, rules over every germ (cause), over all forms, and over all germs; it is he who, in the beginning, bears in his thoughts the wise son, the fiery, whom he wishes to look on while he is born.

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