Bhagavad Gita Bhasya (Gambhirananada)

to be; the hetuh, cause, in the sense of being the
originator. Thus, by virtue of being the source of
body and organs, Nature is the cause of mundane
existence. Even if the reading be karya-karanakartrtva,
karya (effect, modification) will mean
anything that is the transformation of something;
and karana (cause) will be that which becomes
transformed. So the meaning of the compund will
be: 'with regard to the source of the effect and the
cause'. Or, karya means the sixteen [The eleven
organs (five sensory, five motor, and mind) and the
five objects (sound etc.).] modificaitons, and karana
means the seven [Mahat, egoism, and the five
subtle elements.] transformations of Nature. They
themselves are called effect and cuase. So far as the
agentship with regard to these is concerned Nature
is said to be the cause, because of the same reason
of being their originator. As to how the soul can be
the cause of mundane existence is being stated:
Purusah, the soul, the empirical being, the knower
of the field-all these are synonymous; is the hetuh,
cause; bhoktrtve, so far as enjoyership, the fact of
being the perceiver; sukha-duhkhanam, of
happiness and sorrow-which are objects of
experience, is concerned. How, again, is it asserted
with respect to Nature and soul that, they are the
causes of mundane existence by virtue of this fact
