Chapter VIII · Śloka 4
अधिभूतं क्षरो भावः पुरुषश्चाधिदैवतम् ।
अधियज्ञोऽहमेवात्र देहे देहभृतां वर ॥
अधियज्ञोऽहमेवात्र देहे देहभृतां वर ॥
adhibhūtaṃ kṣaro bhāvaḥ puruṣaś cādhidaivatam |
adhiyajño'ham evātra dehe deha-bhṛtāṃ vara ||
adhiyajño'ham evātra dehe deha-bhṛtāṃ vara ||
Adhibhūta is the ever-changing physical domain; the cosmic Puruṣa is adhidaiva; and I alone am adhiyajña here in this body, O best of the embodied.
The perishable material world is adhibhūta; the cosmic Puruṣa (Hiraṇyagarbha) is adhidaiva, the presiding deity of all senses; and the Supreme Lord himself, as the inner witness, is the adhiyajña — the ground of all sacrificial action.
