Dvesha is a big word that means "disliking" or "avoiding" in Buddhism. When something or someone doesn't make us happy or feel good, we may develop dvesha towards it. For example, if we don't like broccoli, we may say we have dvesha towards broccoli.
Sometimes, we have dvesha towards things that we shouldn't have it towards, like people who are different from us or situations that are beyond our control. Buddhism teaches us to recognize when we have dvesha and to practice letting it go so that we can be happier and more peaceful.
To practice letting go of dvesha, we can practice mindfulness, which means being in the present moment and being aware of our thoughts and feelings without judging or reacting to them. We can also practice compassion towards ourselves and others, which means being kind and understanding rather than critical or judgmental.
Overall, dvesha is just a fancy word for not liking something, but it's important to be mindful of our dvesha so that we can learn to let go of it and be happier.
