Bhagavad Gita 8.4

अधिभूतं क्षरो भवः पुरुषश्चाधिदैवतम् |
अधियज्ञोऽहमेवात्र देहे देहभृतां वर

Translation

O best of the embodied souls, the physical manifestation that is constantly changing is called adhibhūta; the universal form of God, which presides over the celestial gods in this creation, is called Adhidaiva; I, who dwell in the heart of every living being, am called Adhiyajna, or the Lord of all sacrifices.
