5.4

Translation by Swami Sivananda
4 If, again, he meditates on the second letter, he attains the mind and is led up by the yajur verses to the intermediate space, to the Plane of the Moon. Having enjoyed greatness in the Plane of the Moon, he returns hither again. 

Translation by Max Mueller
4. If he meditate with two Mâtrâs (A + U) he arrives at the Manas, and is led up by the Yagus-verses to the sky, to the Soma-world. Having enjoyed greatness in the Soma-world, he returns again.
