Translation: 
The Lord appeared as the Hayagrīva incarnation in a sacrifice performed by me [Brahmā]. He is the personified sacrifices, and the hue of His body is golden. He is the personified Vedas as well, and the Supersoul of all demigods. When He breathed, all the sweet sounds of the Vedic hymns came out of His nostrils.
Purport: 

The Vedic hymns are generally meant for sacrifices performed by fruitive workers who also want to satisfy the demigods to achieve their fruitive result. But the Lord is the personified sacrifices and personified Vedic hymns. Therefore one who is directly a devotee of the Lord is a person who has automatically both served the purposes of sacrifices and pleased the demigods. The devotees of the Lord may not perform any sacrifice or may not please the demigods as per Vedic injunctions, and still the devotees are on a higher level than the fruitive workers or the worshipers of different demigods.
