। ॥ ६९ ॥
In plain words
You alone master Gati, the movement of melody, Gamaka, its ornament, and Gīta, song itself. Three lines shine on your throat, keeping count of the fine strands knotted there at your wedding. They are like the boundaries of the three Grāmas, tonal systems from which every sweet Rāga is drawn.
Close to the Sanskrit
O sole adept in Gati, melodic movement, Gamaka, ornament, and Gīta, song: three lines shine on your throat, guaranteeing the count of the finely twisted threads tied at your wedding, like boundaries fixing the stations of the three Grāmas, tonal systems from which many kinds of sweet Rāga arise.
