Bṛhadāraṇyakopaniṣadbhāṣyam

Verse 101

इयं पृथिवी सर्वेषां भूतानां मध्वस्यै पृथिव्यै सर्वाणि भूतानि मधु यश्चायम-स्यां पृथिव्यां तेजोमयोऽमृतमयः पुरुषो यश्चायमध्यात्मं शारीरस्तेजोमयोऽमृत-मयः पुरुषोऽयमेव स योऽयमात्मेदममृत-मिदं ब्रह्मेदं सर्वम् ॥ १ ॥

In plain words

This earth is honey to every living thing, and every living thing is honey to this earth. The shining, deathless being who lives in this earth, and the shining, deathless being who lives in your own body -- they are the very same one. This is the Self. This is what never dies. This is Brahman. This is everything.

Close to the Sanskrit

This earth is honey for all beings, and all beings are honey for this earth. And the being who, in this earth, is made of light and made of immortality, and the being who, within the body, made of light and made of immortality, is bodily -- this indeed is that one; this is the Self; this is the immortal; this is Brahman; this is everything.
