Imagine that you are watching a birds egg hatch. At first, the egg appears to be a solid object with a clear form and identity. However, as the bird inside the egg begins to develop and grow, the eggshell starts to crack and break apart. Eventually, the bird emerges from the egg and the shell is discarded.
Through this process, we can see that the eggshell was not a static, permanent object. It was simply a temporary form that was necessary for the development and growth of the bird embryo. Similarly, we can understand that all phenomena are impermanent and lack a fixed, inherent self-nature.
This recognition of emptiness can be applied to our own sense of self and identity. Just as the bird in the egg was not a fixed, permanent entity, neither are we. Rather, we are constantly changing and evolving, dependent on various conditions for our existence. By understanding emptiness through this example, we can develop a greater sense of wisdom, compassion, and freedom in our lives. We can start to let go of our attachment to fixed ideas and identities, and embrace the impermanence and interdependence of all phenomena.
