अयं वायुः सर्वेषां भूतानाम् मधु, अस्य वायोः सर्वाणि भूतानि मधु; यश्चायमस्मिन्वायौ तेजोमयओऽमृतमयः पुरुषः, यशायमध्यात्मं प्राणस्तेजोमयोऽमृतमयः पुरुषः, अयंएव स योऽयमात्मा, इदम् अमृतम्, इदं ब्रह्म, इदं सर्वम् ॥ ४ ॥
ayaṃ vāyuḥ sarveṣāṃ bhūtānām madhu, asya vāyoḥ sarvāṇi bhūtāni madhu; yaścāyamasminvāyau tejomayao’mṛtamayaḥ puruṣaḥ, yaśāyamadhyātmaṃ prāṇastejomayo’mṛtamayaḥ puruṣaḥ, ayaṃeva sa yo’yamātmā, idam amṛtam, idaṃ brahma, idaṃ sarvam || 4 ||
4. This air is like honey to all beings, and all beings are like honey to this air. (The same with) the shining, immortal being who is in this air, and the shining, immortal being who is the vital force 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.
Likewise air. It is the vital force in the body. The elements are called honey, because they help by furnishing materials for the body. While the beings, shining and so forth, residing in them are called honey, because they help by serving as the organs. As has been said, ‘The earth is the body of that organ of speech, and this fire is its luminous organ’ (I. v. 11).
