"The direction of the heart, a reed to sail" is a quote from Qi Jinian's work "Dust Song." In this piece, the phrase is used to express a firm belief and determination—that no matter where the heart longs to go, one will bravely take the first step. Even if only a small boat (a reed), one must steadfastly sail forward. It describes the resolve to reach one's faith, regardless of how difficult the journey may be.
