Starting from having thoughts imbued with the three poisons, one would have intentions and intentions lead to kamma by way of actions, speech and thoughts.
All mental phenomena have mind as their forerunner;
they have mind as
their chief; they are mind-made. If one speaks or acts with an evil
mind, 'dukkha' follows him just as the wheel follows the hoofprint
of the ox that draws the cart.
Dhp 1
"Intention, I tell you, is kamma. Intending, one does kamma by way of
body, speech, & intellect.
AN 6.63
“Mendicants, there are these three unskillful roots. What three?
Greed, hate, and delusion.
Greed is a root of the unskillful. When a greedy person chooses to act
by way of body, speech, or mind, that too is unskillful. When a greedy
person, overcome by greed, causes another to suffer under a false
pretext—by execution or imprisonment or confiscation or condemnation
or banishment—thinking ‘I’m powerful, I want power’, that too is
unskillful. And so these many bad, unskillful things are produced in
them, born, sourced, originated, and conditioned by greed.
Hate is a root of the unskillful. When a hateful person chooses to act
by way of body, speech, or mind, that too is unskillful. When a
hateful person, overcome by hate, causes another to suffer under a
false pretext—by execution or imprisonment or confiscation or
condemnation or banishment—thinking ‘I’m powerful, I want power’, that
too is unskillful. And so these many bad, unskillful things are
produced in them, born, sourced, originated, and conditioned by hate.
Delusion is a root of the unskillful. When a deluded person chooses to
act by way of body, speech, or mind, that too is unskillful. When a
deluded person, overcome by delusion, causes another to suffer under a
false pretext—by execution or imprisonment or confiscation or
condemnation or banishment—thinking ‘I’m powerful, I want power’, that
too is unskillful. And so these many bad, unskillful things are
produced in them, born, sourced, originated, and conditioned by
delusion. Such a person is said to have speech that’s ill-timed,
false, meaningless, not in line with the teaching and training.
