Sanskrit: यदुच्छ्वासनिःश्वासावेतावाहुती समं नयतीति स  समानः । नो हवाव यजमानः । ष्टफलमेवोदानः ।  एनं यजमानमहरहर्ब्रह्मगमयति  
English:  4  Samana is so called because it distributes equally the two oblations, namely, the out breathing and the in breathing; it is the priest. The mind, verily, is the sacrificer. Udana is the fruit of the sacrifice, because it leads the sacrificer every day, in deep sleep, to Brahman.
