Sūtra translation
(The soul too) is an agent, for (then only) scripture (consisting of permission and prohibition), has a (real) pur- port ; (otherwise scripture would be purportless).
If the soul should not be an agent, there would re- sult that scripture has no purpose to serve. Therefore the individual soul also is an agent.
