Returning the hearing to hear self-nature, entering the stream renouncing the object

I think one really needs to have meditation to hear the soundless sound or the sound of meditation to really understand "entering into the self, transcending while not separating from the self. Returning the hearing to hear self-nature.

Self-nature means our own every individual's own Buddha-nature which is "emptiness" and which is non-attachment, neither existence nor non-existence.

Buddhism teaches about negating the self without losing the self; namely, it means non-attachment to the self, transcending while not separating from the self. This reflects the idea of “entering into the stream while renouncing the object”, or “returning the hearing to hear self nature”.
