'Will (saṅkalpa) is better than mind. For when a man wills, then he thinks in his mind, then he sends forth speech, and he sends it forth in a name. In a name the sacred hymns are contained, in the sacred hymns all sacrifices.

In plain words: Will, meaning firm intention or resolve, is greater than the mind. First a person resolves, then thinks, then speaks, and the words come out as names, which hold the sacred hymns and rituals.
