There are many kinds of negativity that can interfere with a comfortable mind. According to medical professor and mindfulness expert Jon Kabat-Zinn, the most common interlopers are aversion, apprehension, greed, and fear. Fortunately, mindfulness exercises can help change that. Simply sitting quietly and surrendering to our feelings can help us become better, more reasonable people. Even though there is suffering in the world, it’s important to hold onto the fact that life is a gift.
