Seon, also known as Zen, is a Korean meditative tradition that is deeply rooted in the teachings of Buddhism. It emphasizes the practice of meditation and self-reflection as a means to attain enlightenment and liberation from suffering. The core teachings of Seon can be summarized as follows:

1. Non-duality: Seon emphasizes the concept of non-duality, which means that there is no separation between the self and the world. This idea challenges the commonly held belief that we are separate from our surroundings and encourages us to see the interconnectedness of all things.

2. Mindfulness: Central to Seon practice is the cultivation of mindfulness, which involves being fully present and aware in the present moment. By being mindful, we are able to see things as they are, without judgment or attachment.

3. Emptiness: Seon teaches the concept of emptiness, which refers to the idea that all things are impermanent and lack a fixed, inherent nature. This understanding helps us to let go of attachments and expectations, leading to a more peaceful and contented state of mind.

4. Non-attachment: Seon teaches that attachment to desires and attachments to the self are the root causes of suffering. By practicing non-attachment, we can break free from the cycle of suffering and find true liberation.

5. Self-inquiry: Seon emphasizes the importance of self-inquiry, which involves questioning the nature of the self and the world around us. Through this process of introspection, we can gain a deeper understanding of ourselves and our true nature.

6. Compassion: Compassion is a fundamental teaching in Seon. By cultivating compassion for ourselves and others, we can break down barriers and connect with others on a deeper level, leading to a more harmonious and peaceful world.

7. Direct experience: Seon emphasizes the importance of direct experience over intellectual understanding. Through meditation and self-reflection, we can directly experience the truth of our existence and the nature of reality.

In conclusion, the core teachings of Seon (Zen) revolve around the concepts of non-duality, mindfulness, emptiness, non-attachment, self-inquiry, compassion, and direct experience. These teachings offer a path towards enlightenment and liberation from suffering, ultimately leading to a more peaceful and fulfilled life.
