PrU 4.4
यद् उच्छ्वासनिःश्वासावेतावाहुती समं नयतीति स समानः । मनो ह वावन यजमानः । इष्टफलम् एवोदानः । स एनं यजमानम् अहरहर्ब्रह्म गमयति
yad ucchvāsaniḥśvāsāvetāvāhutī samaṃ nayatīti sa samānaḥ | mano ha vāvana yajamānaḥ | iṣṭaphalam evodānaḥ | sa enaṃ yajamānam aharaharbrahma gamayati
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Because it carries equally these two oblations, the out-breathing and the in-breathing, the Samâna is he (the Hotri priest). The mind is the sacrificer, the Udâna is the reward of the sacrifice, and it leads the sacrificer every day (in deep sleep) to Brahman.
