MUṆḌAKA UPANISHAD · 1.1.7

यथोर्णनाभिः सृजते गृह्णते च
यथा पृथिव्यामोषधयः संभवन्ति ।
यथा सतः पुरुषात्केशलोमानि
तथाऽक्षरात्संभवतीह विश्वम् ॥ ७॥

yathorṇanābhiḥ sṛjate gṛhṇate ca
yathā pṛthivyāmoṣadhayaḥ saṃbhavanti ।
yathā sataḥ puruṣātkeśalomāni
tathā’kṣarātsaṃbhavatīha viśvam ॥ 7॥

As the spider puts out and gathers in, as herbs spring up upon the earth, as hair of head and body grow from a living man, so here all is born from the Immutable.
