Kwan um means „perceive sound.“ This means perceive your true self. At the same time, perceiving world sound means perceiving that many, many beings are suffering. If you can hear this sound of suffering, then helping is both possible and necessary. That is the Bodhisattva Way. Helping other beings is our practice and our job. Correct practicing is not only attaining enlightenment — it’s finding enlightenment’s job.
