Asanga, the founder of Yogachara Buddhism, had a significant impact on the development and spread of this school of thought. He was a renowned scholar and teacher, and his teachings attracted many followers and disciples.

One of Asanga's most notable disciples was his brother, Vasubandhu. Vasubandhu was also a prominent figure in the development of Yogachara Buddhism and is often considered the second founder of the school. He was a prolific writer and philosopher, and his works furthered the understanding of Yogachara teachings.

Another important disciple of Asanga was Sthiramati. He was a scholar and commentator who wrote extensively on Yogachara philosophy. His commentary on Asanga's work, the "Madhyantavibhaga-karika-bhasya," is considered one of the most authoritative texts on Yogachara.

Dignaga, a renowned logician and philosopher, was also influenced by Asanga's teachings. He incorporated Yogachara principles into his own philosophical system, which had a significant impact on the development of Buddhist logic.

Haribhadra, a scholar and teacher in the 8th century, was also a disciple of Asanga. He wrote commentaries on several Yogachara texts, including Asanga's "Abhidharma-samuccaya."

Asanga's teachings also spread to China, where he had many followers and disciples. One of the most famous Chinese disciples of Asanga was Xuanzang, a monk and scholar who traveled to India to study Buddhism and bring back important texts to China. Xuanzang's journey and his translations of Buddhist texts greatly contributed to the spread of Yogachara teachings in China.

Overall, Asanga's teachings and writings had a profound impact on the development of Yogachara Buddhism, and his disciples and followers played a crucial role in furthering his ideas and spreading them to different parts of Asia. Their contributions helped to solidify Yogachara as one of the major schools of Mahayana Buddhism and continue to influence Buddhist thought and practice today.
