Intention, how, and what one practices not a being or external force.
Kamma is also action.
Edit:
Better one
What, what are you saying?
The nun at my local temple and I were talking about this the yesterday actually. The sutta link you posted are the results of cessation of kamma (bad kamma or bad actions that contribute to it one and the same). So if we penetrate the senses or however phrased, the nun was pretty simple, or stop bad deeds, we dont add to bad kamma. Thereby cessation of it.
No sutta contradicts the other.
Your intentional actions by your conscious mind inform your unconscious mind as to what thought patterns your intentions follow, and reinforces those patterns into habits that will become the default when you are not consciously mindful. If you sow skillful habits by acting skillfully when you are mindful, then you will reap skillful habits that become skillful actions that will carry you through when you are not mindful. Likewise, if you sow unskillful or hateful habits when you are mindful, you will eventually reap unskillful actions when you are not mindful, and will do something you might regret. (Karma bites you in the butt.)
Here is a popular western maxim from the 19th Century that reflects this:
“Sow a thought and you reap an action; sow an act and you reap a habit; sow a habit and you reap a character; sow a character and you reap a destiny.”
Compare to
Dhammapada 1:1-2
1. Mind precedes all mental states. Mind is their chief; they are all mind-wrought. If with an impure mind a person speaks or acts suffering follows him like the wheel that follows the foot of the ox.
2. Mind precedes all mental states. Mind is their chief; they are all mind-wrought. If with a pure mind a person speaks or acts happiness follows him like his never-departing shadow.
So, you identify your unskillful habits, bring them into consciousness, and develop a path of practice to end the bad habit/karma and replace it with a skillful habit/karma. (You "confess" all of your bad karma and "hide" all of your good karma.)
Simsapa sutta:
"Therefore, monks, your task is to learn: 'This is Suffering, this is the Arising of Suffering, this is the Cessation of Suffering, this is the Path that leads to the Cessation of Suffering.' That is your task."
