Chapter -13: Kshetra–Kshetragjna Vibhāga Yoga This chapter of 35 verses deals with the body and spirit in the first half, and for the rest, about Prakruti (Nature) and Purusha (Supreme Spirit). One might notice that v10, advocating asceticism to which Krishna was opposed, won't jell with the rest, either contextually or philosophically, and thus should be seen as an interpolation.
