Nārada–Devamata Dialogue on Prāṇa, Apāna, and Udāna
शान्त्यर्थ व्यानमेकं च शान्तिर्त्रह्या सनातनम् । एतद् रूपमुदानस्य परम॑ ब्राह्मणा विदु:,एकमात्र व्यान शान्तिके लिये है। शान्ति सनातन ब्रह्म है। ब्राह्मगलोग इसीको उदानका परम उत्कृष्ट रूप मानते हैं
śāntyarthaṃ vyānam ekaṃ ca śāntir brahmā sanātanam | etad rūpam udānasya paramaṃ brāhmaṇā viduḥ ||
那罗陀说道：“为求寂静，当了知那被调御为一的生命流，名为毗耶那（vyāna）；而寂静本身即是永恒的梵（Brahman）。知梵者以此为乌陀那最上、最胜之相。”

Educational Q&A
Peace (śānti) is not merely a mood but is identified with the eternal Brahman; disciplined understanding of the vital currents (especially vyāna and udāna) is presented as a yogic-ethical means toward that realization.
Nārada is instructing about inner peace and spiritual physiology (the prāṇas), elevating the discussion from practical calming to metaphysical insight by equating true peace with Brahman and citing the view of Brahman-knowers.
