MUṆḌAKA UPANISHAD · 3.2.7

गताः कलाः पञ्चदश प्रतिष्ठा
देवाश्च सर्वे प्रतिदेवतासु ।
कर्माणि विज्ञानमयश्च आत्मा
परेऽव्यये सर्वे एकीभवन्ति ॥ ७॥

gatāḥ kalāḥ pañcadaśa pratiṣṭhā
devāśca sarve pratidevatāsu ।
karmāṇi vijñānamayaśca ātmā
pare’vyaye sarve ekībhavanti ॥ 7॥

The fifteen parts return into their foundations, and all the gods pass into their proper godheads, works and the Self of Knowledge, — all become one in the Supreme and Imperishable.
