चित्तं च दृष्टिं करणं तथान्य -देकत्र बघ्नाति हि लक्ष्यभेत्ता ।किञ्चित्प्रमादे सति लक्ष्यभेत्तु -र्बाणप्रयोगो विफलो यथा तथा ॥ २२० ॥
In plain words
An archer gathers everything onto one point — his attention, his gaze, the bow in his hands, and every other thing that goes into the shot. Let the focus slip even slightly, and the arrow he lets fly is wasted. Just so here.
Close to the Sanskrit
For the piercer of the target binds the mind, and the sight, the instrument, and likewise whatever else, in one single place; and when there is the slightest inattention, that target-piercer's release of the arrow is fruitless — just as it is there, so it is here.
