Permission granted, permission granted in his hand
The possibility exists and it is given to him to choose. The possibility is in his hand. He has the ability to choose (the right of hearing requires action. The opposite is obligatory).
("Everything is expected and the right is given, and the good of the world is judged, and everything is according to the multitude of deeds" - Avot 3:12, and so: "A man wants to hear for his own good, rather than hear for his own good, to forget for his own good, rather than forget for his own good, and the right is given in his hand, if he is to be a fool" - Midrash Tanchuma (Warsha) Parashat B'Shalach Sima'n 19, and so on: "The reason that permission is given to the corrupt, is that it insists on her not to abandon her duty regarding the Holy Sabbath" - Y.L. Peretz/ The Desire for Clothes, Seth, and so on: "Blondon, permission is given to every Jew to speak in the language of his people, that is, in the Jewish language" - Shalom Aleichem/ London, there is no remedy for her except in fire!, Re)
