CHĀNDOGYA UPANISHAD · 3.1.1

असौ वा आदित्यो देवमधु ।
तस्य द्यौर् एव तिरश्चीनवंशः ।
अन्तरिक्षम् अपूपः ।
मरीचयः पुत्राः ॥

asau vā ādityo devamadhu ।
tasya dyaur eva tiraścīnavaṃśaḥ ।
antarikṣam apūpaḥ ।
marīcayaḥ putrāḥ ॥

The sun is indeed the honey of the Devas. The heaven is the cross-beam (from which) the sky (hangs as) a hive, and the bright vapours are the eggs of the bees.

F. Max Müller · The Upanishads, Sacred Books of the East 1 (1879)
