In each situation, it seems to us that the disturbing emotion or suffering that arises in our mind is very solid and powerful. Since it is so intense, it appears to be more powerful than we feel we are. However, if we actually look and meditate on the mind’s nature, we discover that all the things arising in our mind — thoughts, disturbing emotions, sadness, and misery — are [less solid]. If we scrutinize them, looking to see what they really are and where they really are, we will discover they are empty of substance and location. When we look directly at the thoughts, disturbing emotions, and misery that arise in our mind, we cannot find where they are located, or where they came from, or whether they have a shape or color. We never find any of these qualities that all the objects seem to have.
