He who knows what is the property of this Saman, obtains property. Now verily its property is tone only. Therefore let a priest, who is going to perform the sacrificial work of a Sama-singer, desire that his voice may have a good tone, and let him perform the sacrifice with a voice that is in good tone. Therefore people (who want a priest) for a sacrifice, look out for one who possesses a good voice, as for one who possesses property. He who thus knows what is the property of that Saman, obtains property.
In plain words: The true wealth of the chant is a good tone of voice. So a priest who sings at a sacrifice should want a fine, clear voice. People choose a priest with a good voice the way they would choose a rich man. Whoever knows this gains wealth.
