Thus in brief have Kshetra, knowledge, and the object of knowledge been declared. My devotee, knowing this, becomes fit for assimilation with me.  Know nature and spirit both (to be) without beginning, and know all developments and qualities (to be) produced from nature. Nature is said to be the origin of the capacity of working (residing) in the body and the senses; and spirit is said (to be) the origin of the capacity of enjoying pleasures and pains.
