Imagine that you are walking in a park and you come across a tree. You notice that the tree is casting a shadow on the ground. On first glance, you might think of the shadow as a solid, permanent object with a clear form and identity. However, if you were to examine the shadow more closely, you would realize that it is not a static, permanent object. In fact, the shadow is constantly changing in shape and size, and it is dependent on various factors for its existence.

The shadow is created by the tree blocking the light from the sun. As the position of the sun changes throughout the day, the shadow will also change accordingly. Moreover, the shape of the shadow will be influenced by various other factors in the environment, such as objects that enter and exit its path.

If you were to examine the shadow more closely, you would find that there is no inherent self-nature or essence to the shadow. It is simply a temporary manifestation that arises due to various conditions. This recognition of emptiness can help us to see the world in a different way. By recognizing the impermanence and emptiness of all phenomena, including ourselves, we can lessen our attachment to fixed ideas and identities. This can lead to greater wisdom, compassion, and freedom in our lives.
