It is called the Great Liberation by Hearing ....
Therefore read it in the midst of vast congregations.
Through having heard it once,
even though one do not comprehend it,

it should be read over the pillows of all persons who are ill;
it should be read at the side of all corpses:
it should be spread broadcast.
And now it will be!!
