Bhagavad-gītā As It Is · Text 8.4
Brahman, self, karma and the Lord of sacrifice
अधिभूतं क्षरो भाव: पुरुषश्चाधिदैवतम् ।
अधियज्ञोऽहमेवात्र देहे देहभृतां वर ॥ ४ ॥
adhibhūtaṁ kṣaro bhāvaḥ
puruṣaś cādhidaivatam
adhiyajño ’ham evātra
dehe deha-bhṛtāṁ vara
O best of the embodied beings, the physical nature, which is constantly changing, is called adhibhūta [the material manifestation]. The universal form of the Lord, which includes all the demigods, like those of the sun and moon, is called adhidaiva. And I, the Supreme Lord, represented as the Supersoul in the heart of every embodied being, am called adhiyajña [the Lord of sacrifice].
