By our thoughts and words, we constantly create karma. The energy that impacts the other person through our speech is far more powerful than the energy created by our thoughts. Since we create much of our karma by using our tongues, many Buddhist precepts are related to controlling our tongues through right speech. Right speech helps others and opens others' hearts and minds. Ultimately, right speech is that speech that calms, purifies, and motivates our minds, as well as the minds of others, so that all can reach buddhahood.
