Dharma practice mean think what is good and what is bad to change the way we see things
When people say they are unhappy, then of course they lack peace. What reduce this kind of peace, or energy is the negative emotions I’ve mentioned earlier, especially hatred, anger and jealousy. Those are three types of negative emotions in our mind. Whenever those emotions arise in people’s mind, they lose inner peace. When there is not enough peace, you’re unhappy. You are very distressed by these negative emotions. So these negative emotions create negative karmas, create obstacles for one and others as well. Therefore, to understand the harm of these negative emotions is needed to be an honest person, to be a Dharma practitioner.
Try to understand the negative effect of negative emotions is called ‘mind training’ -to change your mind, the way your mind sees things. Otherwise, it’s very difficult to really create good and pure peace in the mind. There is no way to practice Dharma if not reduce negative thoughts. Without changing this [negative] kind of view there is no way to receive power and benefit from Dharma. We have to train our mind and this is called Dharma practice.
What is Dharma practice? Dharma practice is to really change your mind, to change your view, the way you see things. Dharma practice doesn’t mean just sitting there and thinking nothing. But to think what is good, what is important, what is not important, what is negative, what is positive, what brings you real benefit or what brings you obstacles. We have to distinguish between good and bad. This is called very practical Dharma practice, especially for the beginners like us. We have to know this basic understanding of Dharma: How to think correctly, accordingly?
