ŚVETĀŚVATARA UPANISHAD · 6.5

आदिः स संयोगनिमित्तहेतुः परस् त्रिकालाद् अकलो ऽपि दृष्टः ।
तं विश्वरूपं भवभूतम् ईड्यं देवं स्वचित्तस्थम् उपास्य पूर्वम् ॥

ādiḥ sa saṃyoganimittahetuḥ paras trikālād akalo ’pi dṛṣṭaḥ ।
taṃ viśvarūpaṃ bhavabhūtam īḍyaṃ devaṃ svacittastham upāsya pūrvam ॥

He is the beginning, producing the causes which unite (the soul with the body), and, being above the three kinds of time (past, present, future), he is seen as without parts, after we have first worshipped that adorable god, who has many forms, and who is the true source (of all things), as dwelling in our own mind.
