Asanga, the founder of Yogachara Buddhism, was a prominent figure in the development of Mahayana Buddhism. His teachings differed from other forms of Buddhism in several ways, including his emphasis on the concept of "mind-only" and the importance of meditation.

One of the main differences in Asanga's teachings was his focus on the concept of "mind-only" or "consciousness-only." This idea states that all phenomena, including the external world, are ultimately created by the mind. This is in contrast to other forms of Buddhism, which emphasize the concept of emptiness and the idea that all phenomena are ultimately void of inherent existence.

Another key difference in Asanga's teachings was his emphasis on meditation as a means of attaining enlightenment. He believed that through deep meditation and introspection, one could gain a deeper understanding of the true nature of reality and ultimately achieve enlightenment. This was in contrast to other forms of Buddhism, which placed more emphasis on ritual and devotion.

Additionally, Asanga's teachings placed a strong emphasis on compassion and the bodhisattva path. He believed that the ultimate goal of Buddhism was not just personal enlightenment, but also to help others achieve liberation from suffering. This emphasis on compassion and the bodhisattva ideal was a defining characteristic of Yogachara Buddhism.

Another aspect that set Asanga's teachings apart was his incorporation of Indian philosophical concepts, such as the idea of the "storehouse consciousness" and the concept of the "three natures." These ideas helped to further develop the Yogachara understanding of the mind and its relationship to reality.

Furthermore, Asanga's teachings also differed from other forms of Buddhism in their rejection of the idea of a permanent self or soul. Instead, he taught that the self is a constantly changing process and that the ultimate goal is to transcend the notion of self altogether.

In conclusion, Asanga's teachings differed from other forms of Buddhism in their emphasis on the concept of "mind-only," the importance of meditation, the bodhisattva path, and the incorporation of Indian philosophical concepts. His contributions to the development of Yogachara Buddhism have had a lasting impact on the Mahayana tradition and continue to be studied and practiced by many to this day.
