Recitation
8.4 Adhibhuta (knowledge of the elements) pertains to My perishable Nature and the Purusha or the Soul is the Adhidaiva; I alone am the Adhiyajna here in this body, O best among the embodied (men).
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].
