इयं विद्युत्सर्वेषां भूतानाम् मधु, अस्यै विद्युतः सर्वाणि भूतानि मधु; यश्चायमस्यां विद्युति तेजोमयो’मृतमयः पुरुषः, यश्चायमध्यात्मं तैजसस्तेजोमयो’मृतमयः पुरुषः, अयमेव स यो’यम् आत्मा, इदममृतम्, इदं ब्रह्म, इदं सर्वम् ॥ ८ ॥
iyaṃ vidyutsarveṣāṃ bhūtānām madhu, asyai vidyutaḥ sarvāṇi bhūtāni madhu; yaścāyamasyāṃ vidyuti tejomayo’mṛtamayaḥ puruṣaḥ, yaścāyamadhyātmaṃ taijasastejomayo’mṛtamayaḥ puruṣaḥ, ayameva sa yo’yam ātmā, idamamṛtam, idaṃ brahma, idaṃ sarvam || 8 ||
8. This lighthing is like honey to all beings, and all beings are like honey to this lightning. (The same with) the shining, immortal being who is in this lightning, and the shining, immortal being identified with light 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.
So also lightning. In the body, the being identified with the light that is in the organ of touch.
