首楞嚴義疏注經 6.5

6.5

In Sanskrit, it is *avalokiteśvara*, which is translated here as Guan-shi-yin ('Perceiver of the World's Sounds'); its name is established based on subject and object, realm and wisdom. Meeting the Buddha and contemplating the Dharma both derived from his teacher; teacher and disciple succeeded one another without discrepancy. The wisdoms of hearing, contemplation, and cultivation are the common path for all practices; there is no Buddha who does not transform the masses through voice, and no capacity that does not awaken to understanding through hearing the teaching with the ear faculty. For this reason, that Buddha taught him to enter through this.
