Bodhidharma, also known as Daruma in Japan, is considered the founder of Zen Buddhism and his teachings have had a significant impact on this branch of Buddhism. He was an Indian monk who traveled to China in the 5th century and is credited with bringing the teachings of Zen to China.

One of the main teachings of Bodhidharma in Zen Buddhism is the concept of "direct pointing". This means that instead of relying on scriptures or teachings from others, one should look within themselves to find enlightenment. This idea is closely linked to the concept of self-reliance and self-discovery in Zen Buddhism. Bodhidharma believed that the key to enlightenment lies within each individual and it is up to them to find it through self-reflection and meditation.

Bodhidharma also emphasized the importance of meditation in Zen Buddhism. He introduced the practice of "wall-gazing" or "wall-contemplation" where one would sit in front of a wall and meditate for long periods of time. This practice is still widely used in Zen Buddhism today and is believed to help clear the mind and achieve a state of enlightenment.

Another significant teaching of Bodhidharma in Zen Buddhism is the concept of "emptiness". This refers to the idea that all things are impermanent and lack a permanent, independent existence. This concept is closely linked to the Buddhist concept of "non-self", which states that there is no permanent, unchanging self or soul. Bodhidharma believed that by understanding and accepting the concept of emptiness, one can achieve a state of enlightenment and liberation from suffering.

Bodhidharma's teachings also emphasized the importance of living in the present moment. He believed that dwelling on the past or worrying about the future only leads to suffering and that true happiness can only be found in the present moment. This concept is closely connected to the practice of mindfulness in Zen Buddhism, which encourages individuals to be fully present and aware in each moment.

In addition to these teachings, Bodhidharma also emphasized the importance of the relationship between a teacher and student in Zen Buddhism. He believed that a true teacher should not rely on words or scriptures, but rather guide their students through their own personal experiences and understanding.

Overall, Bodhidharma's teachings in Zen Buddhism have had a profound impact on the practice and philosophy of this branch of Buddhism. His emphasis on self-discovery, meditation, emptiness, living in the present moment, and the relationship between a teacher and student continue to be core principles in Zen Buddhism today.
