By devotion. Of what kind of devotion? He says: by undivided devotion, devotion not held apart, the devotion which never goes anywhere apart from the Blessed Lord; the devotion by which, with all the instruments, nothing is perceived other than Vāsudeva. By that devotion I, of such a kind, in the manner of the universal form, can, O Arjuna, be known from the scriptures; not only known from the scriptures, but seen, made present in direct vision, in truth, as I truly am; and entered into, and reached as liberation, O scorcher of foes. Now the meaning that is the essence of the whole scripture of the Gītā, the meaning that aims at the highest good, is told, gathered together so that it may be put into practice.
