觀音義疏 1.78

1.78

在手名杻、在脚名械、在頸名枷、連身名鎖，此則三木一鐵之名也。繫名繫礙，檢是封檢，繫未必檢，檢必被繫，繫而具檢，憂怖亦深。鳥死聲哀，人死言善，若能稱觀世音者，重關自開，鐵木斷壞。

Those on the hands are called handcuffs; those on the feet are called gyves; that on the neck is called a cangue; that binding the body is called chains. These are the designations of three wooden and one iron [instruments]. 'Bound' means tied and obstructed; 'checked' means sealed and inspected. Being bound does not necessarily mean being checked, but being checked certainly entails being bound; being bound while fully checked, grief and dread are also deep. When a bird is dying, its cry is mournful; when a human is dying, their words are good. If one can call upon Avalokiteśvara, the multi-layered gates will open of themselves, and the iron and wood will break in pieces.
