Dogen, the founder of Soto Zen Buddhism in Japan, had a unique approach to Buddhist teachings that set him apart from other schools of Buddhism. His teachings were heavily influenced by his study of Chinese Ch'an Buddhism and his personal experiences in meditation and contemplation.

One of the key differences in Dogen's teachings was his emphasis on the practice of zazen, or seated meditation. While other Buddhist schools also practiced meditation, Dogen believed that zazen was the most direct and effective way to attain enlightenment. He taught that through the practice of zazen, one could directly experience the true nature of reality and break free from the cycle of suffering.

Dogen also emphasized the concept of "shikantaza," or "just sitting," in his teachings. This meant sitting in meditation without any specific goal or expectation, allowing the mind to settle and become present in the moment. This was in contrast to other schools that focused on specific techniques or methods to reach enlightenment.

Another important aspect of Dogen's teachings was his emphasis on the concept of "non-duality." He taught that there is no separation between the self and the universe, and that everything is interconnected and interdependent. This was a departure from the traditional Buddhist view of attaining enlightenment as a means of transcending the self.

In addition, Dogen's teachings emphasized the importance of everyday activities as a means of spiritual practice. He believed that enlightenment was not something that could only be attained through meditation, but could also be experienced in the mundane tasks of daily life. This concept of "everyday Zen" was a departure from the traditional focus on monastic life and strict adherence to rituals and ceremonies.

Furthermore, Dogen's teachings also differed from other schools in his rejection of the idea of a fixed self or ego. He taught that the self is constantly changing and evolving, and that clinging to a fixed identity only leads to suffering. This concept of impermanence and non-self was a central theme in his teachings.

In conclusion, Dogen's teachings differed from other Buddhist schools in their emphasis on zazen and shikantaza, the concept of non-duality, the importance of everyday activities, and the rejection of a fixed self. His teachings continue to influence the practice of Soto Zen Buddhism and have had a profound impact on the understanding of the true nature of reality.
