In dealing with weeds,
Firm resolution is necessary.

Remains free of blame.

One has certain relations with him, hence there is danger that one may give up the struggle as hopeless. But this must not be. One must go on resolutely and not allow himself to be deflected from him course. Only in this way does one remain free of blame.
