इदं मानुषं सर्वेषाम् भूतानां मधु, अस्य मानुषस्य सर्वाणि भूतानि मधु; यश्चायमस्मिन्मानुषे तेजोमयोऽमृतमयः पुरुषः, यश्चायमध्यात्मं मानुषस्तेजोमयोऽमृतमयः पुरुषः, अयमेव स योऽयमात्मा, इदममृतम्, इदं ब्रह्म, इदं सर्वम् ॥ १३ ॥
idaṃ mānuṣaṃ sarveṣām bhūtānām madhu, asya mānuṣasya sarvāṇi bhūtāni madhu; yaścāyamasminmānuṣe tejomayo’mṛtamayaḥ puruṣaḥ, yaścāyamadhyātmaṃ mānuṣastejomayo’mṛtamayaḥ puruṣaḥ, ayameva sa yo’yamātmā, idamamṛtam, idaṃ brahma, idaṃ sarvam || 13 ||
13. This human species is like honey to all beings, and all beings are like honey to this human species. (The same with) the shining, immortal being who is in this human species, and the shining, immortal being identified with the human species in the body. (These four) are but this Self. (This Self-knowledge) is (the means of) immortality; this (underlying unity) is Brahman; this (knowledge of Brahman) is (the means of becoming) all.
This particular aggregate of body and organs is directed by righteousness and truth. The human and other species are the particular types to which it belongs. We observe in life that all beings are helpful to one another only by belonging to the human or other species. Therefore these species, human and the rest, are like honey to all beings. These too may be indicated in two ways—externally as well as internally.
