Imagine that you are at a beach and have just built a sand tower. You might see the tower as a tangible object with a clear form and identity. However, as time passes, you notice that the sand tower begins to collapse, unable to maintain its structure., You start to realize that the sand tower is not a static, permanent object. It is constantly changing and is dependent on various conditions for its existence. For example, the wind, the sun, and the surrounding environment can affect the shape and stability of the sand tower, and without those conditions, the tower would not exist., In this way, the sand tower represents the Buddhist concept of emptiness, which states that all phenomena lack inherent existence and are dependent on various factors or conditions., Reflecting on the emptiness of the sand tower can help us to recognize the impermanence and transience of all things in life. By realizing that nothing is fixed or permanent, we can learn to let go of our attachment to material possessions, wealth, fame, or our own self-identity. This can lead to a greater sense of peace, equanimity, and wisdom in our lives, as we acknowledge the fluidity of the world around us and embrace the impermanence of our existence.
