The karma of thoughts

[Digity]

Supposing you have an unskillful or even evil thought come up. We can’t necessarily control are thoughts, since they often pop up without us asking for it. Now, if a bad thought comes into the mind is that considered bad karma? Is having a bad thought considered bad? Or is it the way we react to the thought that counts? For instance, if we have the bad thought and then believe it and indulge in it. What if we have the bad thought but afterwards rebuke it and tell ourselves to stop thinking that way then is that considered good regardless of what the bad thought was?

Of course we can. That is what meditation helps you do - 'Bring the Mind home', and maintain a thought process you are watchful of. That's what being 'Mind-ful is. Fully aware of Mind...

All actions generate Kamma, be they mental, verbal or physical.

But thinking of killing someone, is not as bad as threatening them, verbally, is not as bad as harming them physically.

If you act upon the thought, there is a kammic consequence, depending on the level of commitment and response to that initial trigger-thought.

Or so have I heard.

Whenever you want to do a mental action, you should reflect on it: 'This mental action I want to do — would it lead to self-affliction, to the affliction of others, or to both? Would it be an unskillful mental action, with painful consequences, painful results?' If, on reflection, you know that it would lead to self-affliction, to the affliction of others, or to both; it would be an unskillful mental action with painful consequences, painful results, then any mental action of that sort is absolutely unfit for you to do. But if on reflection you know that it would not cause affliction... it would be a skillful mental action with pleasant consequences, pleasant results, then any mental action of that sort is fit for you to do.

While you are doing a mental action, you should reflect on it: 'This mental action I am doing — is it leading to self-affliction, to the affliction of others, or to both? Is it an unskillful mental action, with painful consequences, painful results?' If, on reflection, you know that it is leading to self-affliction, to the affliction of others, or to both... you should give it up. But if on reflection you know that it is not... you may continue with it.

Having done a mental action, you should reflect on it: 'This mental action I have done — did it lead to self-affliction, to the affliction of others, or to both? Was it an unskillful mental action, with painful consequences, painful results?' If, on reflection, you know that it led to self-affliction, to the affliction of others, or to both; it was an unskillful mental action with painful consequences, painful results, then you should feel distressed, ashamed, & disgusted with it. Feeling distressed, ashamed, & disgusted with it, you should exercise restraint in the future. But if on reflection you know that it did not lead to affliction... it was a skillful mental action with pleasant consequences, pleasant results, then you should stay mentally refreshed & joyful, training day & night in skillful mental qualities.

The Blessed One said: "When a monk is intent on the heightened mind, there are five themes he should attend to at the appropriate times. Which five?"
...
"Now when a monk... attending to another theme... scrutinizing the drawbacks of those thoughts... paying no mind and paying no attention to those thoughts... attending to the relaxing of thought-fabrication with regard to those thoughts... beating down, constraining and crushing his mind with his awareness... steadies his mind right within, settles it, unifies it and concentrates it: He is then called a monk with mastery over the ways of thought sequences. He thinks whatever thought he wants to, and doesn't think whatever thought he doesn't. He has severed craving, thrown off the fetters, and — through the right penetration of conceit — has made an end of suffering and stress."

[Mkoll]

Also, part of MN 20 that is before what culaavuso quoted, and is a good approach to these thoughts:

The Blessed One said: "When a monk is intent on the heightened mind, there are five themes he should attend to at the appropriate times. Which five?

"There is the case where evil, unskillful thoughts — imbued with desire, aversion, or delusion — arise in a monk while he is referring to and attending to a particular theme. He should attend to another theme, apart from that one, connected with what is skillful. When he is attending to this other theme, apart from that one, connected with what is skillful, then those evil, unskillful thoughts — imbued with desire, aversion, or delusion — are abandoned and subside. With their abandoning, he steadies his mind right within, settles it, unifies it, and concentrates it. Just as a skilled carpenter or his apprentice would use a small peg to knock out, drive out, and pull out a large one; in the same way, if evil, unskillful thoughts — imbued with desire, aversion, or delusion — arise in a monk while he is referring to and attending to a particular theme, he should attend to another theme, apart from that one, connected with what is skillful. When he is attending to this other theme, apart from that one, connected with what is skillful, then those evil, unskillful thoughts — imbued with desire, aversion, or delusion — are abandoned and subside. With their abandoning, he steadies his mind right within, settles it, unifies it, and concentrates it.

"If evil, unskillful thoughts — imbued with desire, aversion, or delusion — still arise in the monk while he is attending to this other theme, connected with what is skillful, he should scrutinize the drawbacks of those thoughts: 'Truly, these thoughts of mine are unskillful, these thoughts of mine are blameworthy, these thoughts of mine result in stress.' As he is scrutinizing the drawbacks of those thoughts, those evil, unskillful thoughts — imbued with desire, aversion, or delusion — are abandoned and subside. With their abandoning, he steadies his mind right within, settles it, unifies it, and concentrates it. Just as a young woman — or man — fond of adornment, would be horrified, humiliated, and disgusted if the carcass of a snake or a dog or a human being were hung from her neck; in the same way, if evil, unskillful thoughts — imbued with desire, aversion, or delusion — still arise in the monk while he is attending to this other theme, connected with what is skillful, he should scrutinize the drawbacks of those thoughts: 'Truly, these thoughts of mine are unskillful, these thoughts of mine are blameworthy, these thoughts of mine result in stress.' As he is scrutinizing the drawbacks of those thoughts, those evil, unskillful thoughts — imbued with desire, aversion, or delusion — are abandoned and subside. With their abandoning, he steadies his mind right within, settles it, unifies it, and concentrates it.

"If evil, unskillful thoughts — imbued with desire, aversion or delusion — still arise in the monk while he is scrutinizing the drawbacks of those thoughts, he should pay no mind and pay no attention to those thoughts. As he is paying no mind and paying no attention to them, those evil, unskillful thoughts are abandoned and subside. With their abandoning, he steadies his mind right within, settles it, unifies it, and concentrates it. Just as a man with good eyes, not wanting to see forms that had come into range, would close his eyes or look away; in the same way, if evil, unskillful thoughts — imbued with desire, aversion or delusion — still arise in the monk while he is scrutinizing the drawbacks of those thoughts, he should pay no mind and pay no attention to those thoughts. As he is paying no mind and paying no attention to them, those evil, unskillful thoughts are abandoned and subside. With their abandoning, he steadies his mind right within, settles it, unifies it, and concentrates it.

"If evil, unskillful thoughts — imbued with desire, aversion or delusion — still arise in the monk while he is paying no mind and paying no attention to those thoughts, he should attend to the relaxing of thought-fabrication with regard to those thoughts. As he is attending to the relaxing of thought-fabrication with regard to those thoughts, those evil, unskillful thoughts are abandoned and subside. With their abandoning, he steadies his mind right within, settles it, unifies it, and concentrates it. Just as the thought would occur to a man walking quickly, 'Why am I walking quickly? Why don't I walk slowly?' So he walks slowly. The thought occurs to him, 'Why am I walking slowly? Why don't I stand?' So he stands. The thought occurs to him, 'Why am I standing? Why don't I sit down?' So he sits down. The thought occurs to him, 'Why am I sitting? Why don't I lie down?' So he lies down. In this way, giving up the grosser posture, he takes up the more refined one. In the same way, if evil, unskillful thoughts — imbued with desire, aversion or delusion — still arise in the monk while he is paying no mind and paying no attention to those thoughts, he should attend to the relaxing of thought-fabrication with regard to those thoughts. As he is attending to the relaxing of thought-fabrication with regard to those thoughts, those evil, unskillful thoughts are abandoned and subside. With their abandoning, he steadies his mind right within, settles it, unifies it, and concentrates it.

"If evil, unskillful thoughts — imbued with desire, aversion or delusion — still arise in the monk while he is attending to the relaxing of thought-fabrication with regard to those thoughts, then — with his teeth clenched and his tongue pressed against the roof of his mouth — he should beat down, constrain, and crush his mind with his awareness. As — with his teeth clenched and his tongue pressed against the roof of his mouth — he is beating down, constraining, and crushing his mind with his awareness, those evil, unskillful thoughts are abandoned and subside. With their abandoning, he steadies his mind right within, settles it, unifies it, and concentrates it. Just as a strong man, seizing a weaker man by the head or the throat or the shoulders, would beat him down, constrain, and crush him; in the same way, if evil, unskillful thoughts — imbued with desire, aversion or delusion — still arise in the monk while he is attending to the relaxing of thought-fabrication with regard to those thoughts, then — with his teeth clenched and his tongue pressed against the roof of his mouth — he should beat down, constrain, and crush his mind with his awareness. As — with his teeth clenched and his tongue pressed against the roof of his mouth — he is beating down, constraining, and crushing his mind with his awareness, those evil, unskillful thoughts are abandoned and subside. With their abandoning, he steadies his mind right within, settles it, unifies it, and concentrates it.

With a highly untrained mind as most of us have, we give rise to useless unskillful thought all the time. from my experience following after the thought or pushing it away is only a cause for suffering. It is easy to get caught up it the content of thoughts because that is where we live most of the time. I would say have a look at the Satipatthana Sutta and read the Bahiya Sutta. This explains clearly how all phoenomena including thoughts should be handled which leads to true freedom from suffering.
