Thoughts can contribute to karma too

Karma can be formed at any moment through our thoughts. Thoughts, be they good or bad constitute karma too. Hence we should get rid of bad thought or evil thought to prevent forming bad karma and cultivate good thought such as wishing other people succeed in what they are doing, praying the speedy recovery from sickness of someone, etc. If you think of killing someone and before you can do it, you have already formed a bad karma for yourself. Chanting the name of Amitabha Buddha or practicing meditation can help us get rid of thoughts thereby achieving nothingness in our mind. This is also good in avoiding forming bad karma.
