To a large degree, karma depends on the intention behind the words or actions. Is it possible. without attaining enlightenment, to control our intentions and volition to the point where no karma is created?
SHIH-FU:
It is possible, but very difficult. I suppose you would never be able to interact with others. Words spoken and actions performed without volition do not create karma. I am not sure you can speak and act without wanting to speak and act.
STUDENT:
What if I kill a sentient being without knowing it? Suppose I'm driving down a dark street at night and a cat runs under the car before I can react. Is karma created then?
SHIH-FU:
First, you were riding the car by choice. Second, that situation came about because of causes and conditions and because of your karma and the cat's karma. Therefore, karma is created; but the karma is lighter than if you had purposely killed the cat.
STUDENT:
Do random thoughts create karma?
SHIH-FU:
No. Thoughts that come and go of their own accord do not create karma. Only thoughts that arise with volition create karma. Such karma is also lighter than karma created by words and actions.
STUDENT:
What about the willful choice to think about my method of practice, or to think about the welfare of sentient beings? Does that create karma?
SHIH-FU:
Yes, that creates good karma.
