East Asian Yogācāra is a school of Buddhism that originated in India, but was later adopted in countries like China, Vietnam, and Korea. It focuses on understanding how the mind works and how to control it. The main idea is to use meditation and other mindfulness practices to understand the ways that we think and feel, and how to use these insights to become happier and more peaceful. The goal is to gain greater insight into the self and the world, and learn to live with greater love and kindness towards all beings.
