If the internal organ were the agent, then--since it is impossible that
a being other than the agent should be the enjoyer of the fruit of the
action--the power of enjoyment also would belong to the internal organ,
and would consequently have to be denied of the Self. But if this were
so, there would be no longer any proof for the existence of the Self;
for they expressly teach that 'the person (i.e. the soul) exists, on
account of the fact of enjoyment.'
