In Zen, the concept of self is viewed as something that is constantly changing and impermanent. This is in contrast to other belief systems that see the self as a fixed and unchanging entity. Zen teaches that the idea of a permanent self is an illusion and that true understanding and enlightenment can only be achieved by letting go of this illusion.

One of the core teachings of Zen is the concept of "no-self" or "emptiness." This is the idea that there is no inherent self or ego, but rather everything is interconnected and constantly changing. This is often illustrated through the famous Zen koan, "What is the sound of one hand clapping?" The answer to this question is not a literal sound, but rather the realization that the self is not separate from the world around it.

In Zen, the practice of meditation is key to understanding the concept of self. Through meditation, one can quiet the mind and let go of thoughts and attachments, including the idea of a fixed self. This allows for a direct experience of reality without the filter of the ego.

Another important aspect of Zen's view on the self is the emphasis on living in the present moment. The past and future are seen as distractions that prevent us from fully experiencing the present. By letting go of the idea of a fixed self, one can fully immerse themselves in the present moment and experience life as it is, without the limitations of the ego.

Zen also teaches that the self is not separate from others or the world around us. This is reflected in the concept of "oneness," which is the idea that everything is interconnected and interdependent. By understanding this interconnectedness, one can let go of the idea of a separate self and instead see themselves as part of a larger whole.

In conclusion, Zen views the concept of self as impermanent and illusory. Through the practice of meditation and living in the present moment, one can let go of the idea of a fixed self and experience a deeper understanding of reality. By embracing the concept of "no-self" and recognizing our interconnectedness, we can break free from the limitations of the ego and achieve true enlightenment.
