Brihadaranyaka Upanishad 2.54

अयमाकाशः सर्वेषां भूतानां मधु | अस्याकाशस्य सर्वाणि भूतानि मधु | यश्चायमस्मिन्नाकाशे तेजोमयोऽमृतमयः पुरुषः यश्चायमध्यात्मं हृद्याकाशस्तेजोमयोऽमृतमयः पुरुषः | अयमेव स यो अयमात्मा | इदममृतमिदं ब्रह्मेदं सर्वम् ॥

ayam akashah sarvesham bhutanam madhu | asyaakashasya sarvani bhutani madhu | yash chayam asminn akashe tejomayo'mritamayah purushah yash chayam adhyatmam hridyakashas tejomayo'mritamayah purushah | ayam eva sa yo ayam atma | idam amritam idam brahmedam sarvam ||

This space is the honey of all beings, and all beings are the honey of this space. The luminous, immortal being who is in this space, and the luminous, immortal being identified with the space in the heart — he is but this Self. This is the immortal, this is Brahman, this is all.

यह आकाश सर्वभूतों की मधु है और सर्वभूत इस आकाश के मधु हैं। जो इस आकाश में तेजोमय, अमृतमय पुरुष है और जो हृदयाकाश में तेजोमय, अमृतमय पुरुष है — वे दोनों वही आत्मा हैं, यह अमृत है, यह ब्रह्म है, यह सब-कुछ है।
