In plain words
For one who has reached this, there is no gain to be had by acting and no sin in leaving action undone. Nor is there anything, of any kind, that such a one needs to get from any being.
Word for word
For the one who has attained [the Self], there is no gain to obtain through action, nor sin through nonperformance; there is no object of any kind that one needs to obtain through any beings.
